Here's a bit of in-game story lore I had enjoyed from World of Xeen. Wonder if some of the Legacy lore books will be similar in tone:
Once upon a time two necromancers had a little disagreement. The one was named Darkness, and he contended that he was the most powerful, foul, and evil necromancer in all of Xeen. The other fancied himself Death, and Death believed that HE was the most powerful, foul, and evil necromancer in all of Xeen. On the darkest hour of the darkest night in the year, the two necromancers met in a graveyard to settle the question once and for all.
Standing atop the burial mound of a great hero, Darkness began the fight by uttering a string of syllables so foreign to the human throat as to be virtually unpronounceable. So vile and alien were the words spoken by Darkness that the hero beneath the mound heard them and began to dig his way out of his grave to put a stop to the sounds. During all of this, Death had not been idle. He, too, began incantations meant to awaken the dead.
And so, one by one, the dead began to rise from their graves and fight one another between the two necromancers. The carnage was terrible to behold, the losses devastating. One by one the dead fell again, too damaged to do more than twitch or thrash about where they lay. Broken skeletons and corpses began to fill the valley between the burial mounds upon which the necromancers were standing.
The dead began to clamber atop the piled corpses in their efforts to slay the opposing necromancers. But the battle raged on, filling the valley between the mounds 'til morning, then from morning to afternoon, and then again to blackest night. Aye, the battle raged a full five days, filling the cemetery with a stench the world has never known. The armies of the dead dwindled as the supply of working corpses was used up. Soon the bodies had been piled so high that a kind of bridge formed between the two burial mounds, and the necromancers approached each other, urging their remaining servants forward.
Still the killing continued, and the necromancers drew within spittin' distance. And as the last of the walking dead finished themselves off, the two met and came to blows. The exhausted necromancers fought and wrestled over the mountain of corpses when suddenly Death caught hold of Darkness' throat, and Darkness of Death's. There Darkness and Death gasped out their last breath together, dying as one at the very top of the hideous mountain they had created.
