A listing of the Immortals for the Mystara setting.
from the introduction:
There are many Immortals which have an interest wholly or partially in the World of Mystara. And although there will exist many more Immortals, they will rarely or never act in the Mystara part of the Multiverse. Many Immortals have absolutely no interest in Mystara, as they have no origin there. This document contains only the collection of Immortals who have or had an interest and influence in Mystara, direct or indirect. These Immortals might, however, have (often under an other name) in other parts of the multiverse also obtained a following and corresponding influence.
