Treant Guard

Two types of Treants are described in Dota 2 lore. Their relations are unclear.

Treant Protectors
An ancient race, Treant Protectors are motivated by the defense of their sacred homeland, nestled in the mountains beyond the Vale of Augury. They are gigantic in stature, and possess magical abilities. The best known Protector is Rooftrellen.

"Walking Trees"
Described by Rizzrack, a group of "Walking Trees" laid waste to Augury Bay, killing its inhabitants. These walking trees may be reasonably assumed to be the Treant Protectors, for two reasons:
 * Rizzrack's people was evidently a technological one, with the ability to create machinery to cut down trees. From the Treant Protectors' perspective, this would make them a threat, and therefore a target for destruction.
 * Given the similar toponyms of Augury Bay and Vale of Augury, one can assume the locations are close to each other, and therefore the first to be discovered and attacked.
 * The residents of Augury Bay were killed by entangling vines and roots, similar to Treant Protector's.

Contradicting this theory is the fact that Treant Protectors are generally benevolent, resorting to violence only when needed to stop trespassers. Furthermore, only one Protector, Rooftrellen, was sent out into the outside world. However, due to the Treant Protectors' extremely long view of time, more events may have transpired since his departure. was also added to Dota 2 seven months after, making this theory plausible.

Treant Guard
The Treants Guard is a sentient army summoned by. Their relationship to Treant Protectors is unknown.
