Changes

'''Characters''' in the Diablo universe is what makes it interesting. From the [[Diablo game]]s' different [[class]]es to [[NPC]]s and regular inhabitants of Sanctuary introduced from books and comics. They are all what makes the universe of the games.

* Fiction characters (of varying importance)

* Non-Player characters ([[NPC]]s)

===Previous Player characters===

Besides the [[Barbarian]] who is the same character carried over from [[Diablo II]] into [[Diablo III]], character usually have some impact on the environment.

In [[Diablo I]], the three main characters (the {{iw|Monk Monk}} and the other expansion characters are not [[canon]]) are seen as random adventurers entering the [[Tristram]] labyrinths, and each getting some sort of demonic corruption. The [[Rogue]] character turned into [[Blood Raven]], the [[Sorcerer]] turned into [[The Summoner]] and the [[Warrior]] was the one killing [[Diablo]]'s mortal body, plunging the [[Soulstone]] into his own head. He was then completely overcome by the demon, turning him into the [[Wanderer]]. This is pretty well described in [[Deckard Cain's Journal]].

Then starts [[Diablo II]], and a new band of adventuring heroes follows the Wanderer's footsteps to stop him freeing his brothers (and complete the transformation into Diablo). The group of heroes are generally counted as a solid group, with one or more of each class following through the story line. These are semi-anonymous, and as is previously stated, the only Diablo II character to appear in [[Diablo III]] is the Barbarian.

==Non-Player Characters==

[[NPC]]s are characters played by the computer in the [[Diablo game]]s. They usually have proper names, and some sort of background. Most of the important characters in the universe has or will be represented as an NPC in a Diablo game.
