The Demon's Abode is marked by a sign at the entrance. Known as the "entrance to hell", it is swarming with demons and haunted by skeletons.
Located within this area is the Demon's Cave. Inside the cave, there is a demon meditating. He will not attack Olive on entry. He has no interest in her and with his powers he will promptly transfer her back out.
There is a way to get his attention, however. If Olive has something he desires he will be willing to speak with her and hope for a trade.
A special occurrence also happens in the abode every night. Lucifon and his followers like to make merry outside the Demon's Cave. If Olive should camp there, she will likely be woken by their celebration come morning.
