Uldyssian is the central character in the Sin War Trilogy and part of the Diablo lore. He is a farmer who lost most of his family. He is the pawn chosen to begin a terrible shift in the world of Sanctuary.
Background
Uldyssian has Nephalem ancestry within him and has some of their powers. He can do almost anything from changing weather, causing people to explode, creating shields or simply creating a simple ball of light to see through the dark with. He can also teleport himself and others among amping his strength and healing powers as well as transmuting objects. These powers are based on his will, the more desperate and angry he gets the more powerful his abilities are.
To stop Demons and Angels from taking over Sanctuary, Uldyssian created the Edyrem, made up of Nephalem descendants.
