Heart of Nature

The Heart of Nature is a plane of existence in the world of Dota 2. The heart of nature is a generic name for the same place that Leshrac's lore frequently refers to with different names: "nature's blasted core", "heart of all creation", "heart of existence", etc.

Description
The heart of nature, as its name implies, is found only in the depths of nature. It can be accessed by the Chronoptic Crystals, which is implied to be an item that can see through time. That being said, the heart of nature may exist in the future with the following speculations: According to Leshrac's bio, this nature is lurid and vile, its lurid colors possibly reflected in Leshrac's bright and dissonant color scheme. Here, all of nature has become a desolate land made of degraded elements that are out of balance and harmony. Hence, it is a world of chaos.
 * The word "Chronoptic" is a blend of two words: "chrono-" (or "chron-" when used after a vowel) and "optic". This means that they allow the user to see through time.
 * Leshrac used the Chronoptic Crystals to see the heart of all creation. Which implies that he could have only seen that place by seeing through time.
 * In the heart of nature, all of creation has been decayed, purged, tormented, and whatnot. Given that all things decay or deteriorate over time, the heart of nature may exist in the future, and the crystal shows the grim future of all nature.

Impurities
Just like the word "Chronoptic" in Leshrac's lore, the Impurities are not real words. It is a combination of "impure" and the suffix -ity, a suffix which denotes quality or state. Hence, they are actually the impure elements that Leshrac frequently invokes in his voice lines, and not the impurities in chemistry.

These elements are referred to with different names: "impure powers of nature", "impure elements", "witless elements", etc.

The Impurities are just like the classical elements of nature, except that they have been purged and made impure. These impure elements include:
 * Evil winds
 * Tainted water
 * Sinister energies
 * Brittle earth
 * Pink-purple electricity

Notable Inhabitants
is the sole inhabitant of this vile place, since he describes it as a cloister or a place of solitude. As the sole agent and guardian of this foul place, Leshrac's goal is to transform the balanced and harmonious nature of today into the horrible place that he saw in the Chronoptic Crystals by bringing it into chaos. He accelerates the world's decay by blasting the land as a blight on it, debasing all of creation down to its elements,   and then bringing the components that make up its being into nature's core to become one with their evil counterpart   until everything becomes a world of chaos.
