Unholy

I saw something fouler than I've ever seen before.
Something truly unholy.

Why he was willing to slaughter us all.

The formerly green fields lie in war-torn ruins. The formerly living populace is undead. And the formerly brilliant necromancer, the mastermind behind the civil war that drove the ruling council into exile, appears to have gone insane. But rumor spreads of a reason behind his randomness – a reason all survivors of Thay must rally against.
