Arnheim was a High Elf colony situated on the western coast of Naggaroth. It is shielded from the realm of the Dark Elves by the Blackspine Mountains and a large swamp known as the Doom Glades. As is the case with most High Elf colonies, Arnheim has strong ties with the Tiranoc; the realm is the ancestral home of most of its population. To the south of the city lies sea of pine forest known as the Forest of Arnheim.
