Infernal Dimensions

The Infernal Dimensions, together known as Infernus, is the original home world of the demons. The throne room of Thammaron, which is visited in the quests The Golem and Shadow of the Storm, is likely to be in the infernal dimensions. It is, however, not possible to exit the throne room and explore the dimension any further.

Trivia:

 * The fact that the infernal dimensions are referred to in plural seems to indicate that Infernus is in fact a collection of smaller realms or pocket realms.
 * The demon butler, Alathazdrar, mentions being from Infernus.
