Nothl Realm

The Nothl Realm is an ethereal dimension in the world of Dota 2.

Description
This realm can be accessed by potions made of secret ingredients known only to the Dezun Order, but there are many other ways to access the realm as well, including a dose from the Great Pipe. Trips to this realm are said to be harrowing and departures are painful, an extremely dangerous realm where most visitors never return. Those who do return may be driven mad (likely from being unable to comprehend its inverted properties) or gain new abilities and changes to their being, such as powers sourced from the realm or immortality.

In this strange realm, the properties of all things here are inverted. Light and dark are reversed in this realm—the darkness emits a bright glow that illuminates the pitch black light around it. The weakening or encumbering properties of anything in the Nothl Realm will manifest as strength in the Terrene Plane. Even good and evil are reversed in this place.

The Nothl Realm is an afterlife for those who are deeply connected to it or sacrificed to it and a place of rebirth (for those who are deeply connected to it) into the lands of the living.
