Helheim

Helheim (ヘルヘイム) was one of the nine worlds of YGGDRASIL.

Background
Helheim was one of the realms where the heteromorphic races mainly resided in. During the early years of YGGDRASIL, players belonging to heteromorphic races were hunted by various PKers.

Although it was due to the fact that killing heteromorphic players possessed zero penalties, the other players commence this hunt out of disgust for their monstrous characters. Either that or they did it to gain access to special classes which required killing a certain amount of heteromorphic players.

To escape persecution and harassment, many heteromorphic players took refuge in the world of Helheim, where it acted as their sanctuary from other racial players.
