In case you get this quest through a share, like I did, it gets turned in at Light Hope Chapel in EPL.

What is a man? A miserable little chamber of secrets! But enough talk, have at you!
You find him above Attumen's room, past the blacksmith and up the stairway.
When you reach the top, go left through the doorway and you'll see the Chaimber doors ahead.
Mirkblood engages as soon as you open the door.
He spawns lots of adds that deal significant damage, so make sure to move the boss before the spirit adds activate.
Drops a pet for everyone in the raid, as well asbadges andan ilvl 115 item.

Description
Excellent, an experienced adventurer. Precisely what we need. There has been talk from the Kirin Tor guarding Medivh's tower that something is amiss with Karazhan. There is a new power lurking within, one that answers neither to the Guardian's magic nor the Legion. From what they've scouted, it appears it is an elven prince called Tenris Mirkblood, and there is reason to believe he serves the Scourge. Go, my friend, investigate Mirkblood's chamber, and return with any information you might find.
