Felgrim

Felgrim is an undead who has grown weary of the suspicion directed towards him because of their recent treachery. He reacts harshly to any sign of it.

He was ordered to join the Horde militia, but first he embarked on his own sinister mission. Felgrim was the one who gathered ingredients for Putress's blight attack at Angrathar the Wrathgate, though he didn't know at the time what Putress intended.

 * "I assisted Putress in the creation of the new plague used to destroy the living and undead alike. It was I who gathered the materials that formed the grim weapon."
 * "There is no excuse for what I did. My hand helped in creating the plague used at the Wrath Gate. It does not matter whether I knew their intentions or not. If I truly had honor, I would have questioned the Grand Apothecary."
