Diablo 2 greatly expands on Diablo Gold the lore of the Diablo world. The game's opening cinematic shows that the protagonist in the first Diablo game called The Wanderer, has lost the battle against Diablo. He now seeks to revive Hell's other prime evils, Diablo's Brothers Mephisto and Baal. Diablo tricks a man named Marius into regaining Baal's Soul Stone, but the archangel Tyrael, Aspect of Justice, tasks him with bringing the stone into the Hellforge and destroying it. The participant, working with Tyrael follows in the footsteps of The Dark Wanderer, trying to halt the return of the evils. On the way, the player defeats several lesser evils, but eventually The Dark Wanderer succeeds in resurrecting Mephisto and regaining his form since Diablo. The participant can defeat both and ruin their Soul Stones in the Hellforge, making sure they could never return.

In Diablo 2's expansion, the last remaining wicked tricks Marius into giving him his Soul Stone. This permits him to return to strength, and he begins a siege. Although the protagonist proved successful, Baal is still able to corrupt the Worldstone, leaving Tyrael with no other option but to destroy it.

After a lengthy wait, Blizzard released Diablo 3. Fans discover that there's a gap between Diablo 2 and Diablo 3, and in peace, the world was together with the three evils defeated. All this varies, however, when a falling star crashes into the old palace in Tristram (exactly the same cathedral from Diablo), and risen dead start pouring out. Diablo 3 gives a lot of context to Diablo's events. It's shown that the archbishop Lazarus kidnapped King Leoric's oldest son and turned him into Diablo. The unknown warrior the player controls throughout the course of the game is really the king's youngest son, Aiden. This means that throughout the course of Diablo, the personality must kill the corrupt spirit of his father as the Skeleton King and his brother since Diablo.

The player character arrives at Tristram, seeking block the horde of undead flowing out of it and to buy Diablo Immortal Gold learn the mysteries of this fallen star. The protagonist discovers that the fallen star is a man after defeating the spirit of the slain Skeleton King. It revealed that this man is none other than Tyrael, the Aspect of Justice. The player then finds that Leah's mom, Adria the witch (from Diablo), remains living.
