Morgan Webb of G4’s X-Play gives us a little preview and some interesting info on Blizzard’s upcoming World of WarCraft expansion Wrath of the Lich King. Spoiler alert: Arthas is really a good guy and Death Knights are Paladins in disguise.

Seriously, though, there are some spoilers in the video, so carefully consider whether or not you want to ruin the excitement of starting a Death Knight by knowing what happens ahead of time. You’ve been warned.
