[[Nightmare Caves]] is part of a massive cave system underneath the [[Povus]] region. It is connected to [[Forthragarian Caves]] and [[Elven Judgement]]. Trainers for the majority of the level 90 unlocks can be found in these caves. You can teleport to these trainers if you have [[Teleportation]] at level 25 and use code 0092 in any [[Teleportation Machine]].
