Name: Alatar (Quenya), Morinehtar (the name used for him in Middle-earth)
Age: Since the beginning of time, present in Middle-earth for at least one Age of the Sun
Gender: Male
Father/Mother: Eru Iluvatar (guess where I got my username from...)
Race: Maiar, in human form (Istar, a.k.a Wizard)
Appearance:
Technically, this is supposed to be Pallando. But he likely looks the same anyway, so there :P
Current purpose: En route to Valinor, as he has completed his task in aiding the Free Peoples of Middle-earth. Unfortunately, it appears that Dagor Dagorath (which is the apocalypse scenario I assume you are referring to) is about to begin, and he must aid the remaining Elves, Dwarves and Men (and Hobbits...) in their survival. He adopts a role similar to Gandalf's, going by the name of Morinehtar.
