Szadek

Szadek was the parun (founder) of House Dimir, the blue-black flavored guild of Ravnica. The last of an ancient race of psychic vampires, he has resided in the shadows for ten millennia in an effort to eventually seize control of the entire city. He was the main antagonist, although not realized until far into the story, of the first Ravnica novel.

His equivalent card in the game is Szadek, Lord of Secrets. It is deemed exceedingly powerful when used correctly and combines its abilities with Vulturous Zombie to devastating effect.
