Fabric of Creation

The  (also known as the fabric of nature, mesh of reality, cosmic weave, cosmic tapestry, pattern, etc.) is an important world structure of Dota 2.

Description
The existence of this universe and many other worlds just like ours are all supported by this essential fabric of creation. Any damages done to it will eventually result in the unravelling of the weave, thus unmaking entire worlds if it's neglected. Hence it is the work of the Weavers to repair the worn spots in the pattern and maintain its pristine condition by keeping it tightly woven and unfaded, as well as defending it from the otherworldly pests that gnaw and lay their eggs in the frayed regions of their tapestry, whose brood can quickly devour an entire universe if the Weavers let their attention lapse. Although it is the job of the Weavers to maintain the fabric, it was the Loom who created the threads that form the whole fabric that encompasses all. Wide though it may be, the fabric of one reality ends at its seams where it is joined with the edge of another fabric. These seams of reality are also known as the "twist between worlds" which may or may not be the same as the "web between worlds" that an aspect of Spectre is knowledgeable about. The fabric of reality also acts as a barrier between the planes. Speaking of the twist between worlds, this twist might also be the maze between realities mentioned in Dark Seer's lore. It seems that the weave itself may be dangerous to the Weavers and others who are made of it, since they can be caught and entangled in their own weaves or its threads. implies that the structure of the fabric of planar space can affect the trajectory of arcane energies travelling on it, like curvatures in spacetime fabric affecting the path of light. For example, a pocket where the fabrics of the planes converge creates an area where arcane energies are forced to flow towards it, with no hope of going the other way, like water down a funnel or light into a black hole.

Threads and Fabrics
The fabric of reality is a very complex structure, woven by both young and experienced weavers alike with varying levels of skill. There are lots of threads that constitute the weave, but there are only a few of them that are known. It would appear that each of these threads are woven into their own unique fabric rather than all of them being woven into one whole heterogeneous weave. Here are the following threads and their respective fabrics:
 * The threads of time that compose time's weave. A timeline might be a pattern composed of time threads. These threads may also compose the fabric of spacetime.
 * Akin to a tightrope, Weavers can crawl forward and backwards in time by creeping along the threads of time.
 * Weavers can also travel through the vast fabric of spacetime by using small wormholes that allows them to slip through time.
 * Opening a gap in the spacetime fabric causes young Weavers to slip forth, suggesting that they live in or beyond this fabric.
 * Lastly, this weave of time may exist on an astral level, just like the astral Loom that might have woven it. According to Inai, the map of all time is in the astral plane, appearing as a multitude of lines that streak across said plane. It's possible that, from his perspective, he sees all of time as a bunch of lines rather than a weave made of threads.
 * The threads of strife, woven into the very fabric of conflict. The exiled Skitskurr plans to use these threads to create his soon-to-be realized pattern, sourcing it from the tatters of a future conflict. This conflict could possibly be the battle of the Ancients or even the anticipated war that will happen in the great confluence.
 * The predestined threads of fate. Struggling against fate will provoke a commensurate response that's unpleasant and unfavorable.
 * The threads of life a.k.a. vital threads (which may or may not include the soul thread, a thread that is spooled rather than woven  ) which are woven into the patterns of life or spooled into a roll. Fate is what weaves the threads of everyone's lives together, but it also cuts them short with its blade.

Other Fabrics
There are also other kinds of fabrics in existence that have no known corresponding threads. Because of this, it's unknown if they are actually part of the cosmic tapestry, but, they will be listed here just in case.
 * The fabric of order
 * The fabric of the mind
 * The fabric of the void
 * The fabric of the Rift

The Great Confluence
The Great Confluence is a cataclysmic event in an unseeable point in the future, where the fabrics of multiple realities are fated to collide and merge. It is portended by a multitude of distortions in the fabric of the void, followed by utter chaos and ripples of destruction that will spread throughout all planes of existence,  as well as the contamination of multiple fabrics with each other.

In Dota: Dragon's Blood
Spacetime was briefly alluded to by Slyvion (this intermediate form betwixt Davion and Slyrak that is controlled by the latter) in the animated series of Dota: Dragon's Blood, in the 4th episode "The Monster at the End of this Book" in Book One. Captured by Kaden and chained in the heart of a Dragon Knight redoubt, Slyvion forewarns him about the consequences in destroying an Eldwurm. If he were to kill Slyrak, he would also be toppling a pillar of creation. This would also destroy existence as we know it: time and space, the Manifold Forms, the pillars of order and chaos, all gone. The infinite macrocosms will be destroyed with no renewal to follow. And not even nothing will exist.

Keepers
A number of entities keep the fabric safe and maintain it. Only three of them are known, the best known ones being the Weavers, followed by the Loom and the unnamed guardians. The weavers are a species of extra-dimensional beetles who are charged with the protection and maintainment of the fabric. The best known member of these beetles is Skitskurr, the rogue, who was exiled from the pattern by the guardians after he tossed his duties aside to create his own fabric which pulled against the pattern that the great Loom had woven long ago. The broods of the Weavers dwell in the spacetime fabric. Weavers use the energies of creation to reweave the stuff of reality, but only once it's hot and malleable then it is ready to use. Although it is the Weavers who protect and maintain the fabric of reality, it was the Loom that created it all. Only a few beings can use it to influence the pattern, which may include the Weavers and the guardians. The Loom exists on an astral level. Lastly, the mysterious guardians are a group of beings who protect the fabric. All we know about these guardians is that they have scissors which they use to purge rogue patches that pull against the fabric of creation that the Loom had woven, and then repair that gap in the fabric by reweaving it–which was the case with Skitskurr and his attempt to create his own world. These guardians might be the personification of Fate that Weaver talks about, who also weaves threads together and cuts threads with a blade.

Heroes
As the Fundamental of gravity, can manipulate the fabric of spacetime. His most notable effect on spacetime is the gravitational version of time dilation as well as a pair of golden bracers that he acquired from Cedric that can manipulate the fabric of spacetime itself. Because of his extra-dimensional existence, Darkterror the can influence the very fabrics of reality, especially the fabric of spacetime. 's manipulates the structure of spacetime with waves of pink and orange energy (possibly the Chronoptic energies), destroying lesser beings around him.
 * Enigma frequently refers to his pattern which is implied to be his physical form that's made of void and shadow. It is unknown if his pattern refers to the fabric of reality itself (which implies that his form is made of the stuff of the cosmic fabric if this is the case). Apparently, his pattern is also his consciousness, which disappears when he dies.  This isn't permanent, though, because his pattern will eventually reform out of chaos.
 * Here is a small list of Darkterror's abilities that have the power to warp the fabric of reality to his advantage.
 * From one spot to another, Darkterror rips a hole in time to take a through his timeless home realm Claszureme, allowing him to appear back in an instant without crossing the space between his previous position and his destination.
 * His ultimate is a blister in spacetime that contains a rift to Claszureme where time does not flow, trapping anyone within it in a state of stasis.
 * He may also channel the fabric of the "Rift" to warp his intellect and form, but it is unknown if the Rift's fabric is included in the cosmic tapestry.
 * He seems to know his fate thread, since he mentions seeing his “path” unspooling in front of him. His apotheosis freed him from fate and gave him his own destiny to control.

discovered a simple trick that allowed him to manipulate four-dimensional space in order to affect the happenings in his own.

Despite appearing as a brutish creature, the is capable of bending aspects of nature to his iron will, a prowess that is  a combination of his cunning and strength. Having mastered the arts of the Dark Rift, the may use this foul magic to twist into the seams of reality to project his manifest hatred and malice, conjuring a bottomless  that paralyzes anyone caught within it. His is a corrupted flame that is also conjured through the twist between worlds. The true form of encompasses all with its omnipresence, including every thread of fate that was, is, and will be woven. When appearing unto the material universe he assembles his physical form from the fabric of his true self. The effect's of 's can manipulate space-time over a vast area, impairing entire armies.
 * Barathrum doesn't just rely on his brute strength to get things done, some of his abilities can twist the fabric of reality to facilitate his success.
 * To through this plane unimpeded, Barathrum can warp the fabric of reality around him to lessen its negative influence on his physical form.
 * His unyielding focus forms a centered on him, creating a point of convergence in planar space where not even the strongest arcane energies can escape.
 * His powers over this fabric is further demonstrated by his brute strength which allows him to pry open the rifts between the worlds.

Last but not least, has many powers over the fabric of nature as both its keeper and its future destroyer to make room for his new fabric.
 * Although Skitskurr has been deprived of his duties as a Weaver, he still retains their skills and power. His abilities manipulate the fabric of reality to his advantage in battle.
 * Skitskurr tears a hole in the spacetime fabric, from whence of young Weavers spills forth to latch on to his enemies, eating them alive.
 * He can achieve by slipping into the small wormholes that Weavers go through to slip through time, allowing them to work at their fabric better.
 * Carefully crawling forward on the thread of time, he can walk backwards and travel back in time via  to right the wrongs of his current reality.
 * Besides these, Weaver has many vast powers over the fabric of creation and its many threads. He is one of the few beings with access to the Loom and the skill to use it to weave. His bare arms are his finest and most reliable manipulators, which have been deftly weaving the fabric since time immemorial.
 * He plans to weave the threads of strife (taken from the tatters of a future conflict, perhaps the Ancients' war) into a pattern that he has yet to realize.
 * He is capable of weaving the threads of fate by his own hands, weaving the fates of his enemies into bad ends.
 * Skitskurr's senses are finely tuned to the slightest defections in the fabric of creation, allowing him to be alerted quickly and react accordingly. His carapace is also tuned to the heat and malleability of the energies of creation. It alerts him when these energies are hot and malleable, prompting him to start weaving with these ready-to-use energies.

Devices
The Lost Order is a defunct school of Mastery that was established before the apex of the Isle of Masks, who once had the skills to use their blades to pierce the fabric of reality. One of their lost swords resembles the, which is now in the 's hands. The final issue of eleven generations of bladesmiths, Craler was an elder smith who completed his family's work in crafting a powerful sword that was sharp enough to tear holes in the fabric of reality, creating rifts that can be used for time travel. Tearing a rip in reality that lead to the past a few moments ago, he slew his past self who had just finished the blade and stole it from his past self, but was killed when his paradoxical past caught up to him. These twin blades were recovered by the who gave it to the  to aid her in her multiversal contract killing. Cedric was an alchemist who crafted a pair of golden bracers capable of manipulating the spacetime fabric. After his dark conversion, it was taken by the Enigma. The Continuum Device is said to be capable of bending both space and time to shape infinite realities and summoning alternate versions of its user from the multiverse should they tamper with it, among other amazing and horrifying uses.

Items
According to the, the can cut through space. Perhaps he means the space between the user and their destination is negated, hence it's cut.

Time and space bend before the winged to work its powers of nigh-omnipresence via teleportation that it grants to its wearer.

Weaver found a just beyond the rift when he slipped through time. Its existence beyond time was shocking enough to be described as impossible.
