Revenant Jima

In Ultima Online, Revenant Jima is a small island on the Tokuno Islands, located directly north of Homare-Jima.

Description
The island of Revenant Jima is one place that the adventurer wants to avoid, as the name-giving Revenants are strong spellcasters that can kill even experienced adventurers quickly. To make things worse, they also command an army of undead to secure their home against intruders and dying on this remote island is most likely fatal, with no healer anywhere close.

Is therefore should be best to avoid it entirely.
