A rare monster in Terminus. He can be found in the middle of the cave filled with hulking phantasms within The Sinkhole. During the standard quest line you are required to go into this cave. He is a rare mob and so has a very long spawn time.
He drops a basic dagger that can easily be replaced with a more powerful one as you leave Terminus. The only reason to acquire the dagger is for the aesthetic value that very few people will be willing to waste their time obtaining it or those who do will likely sell it for the inventory slot.
