My players named the nothic frank. oh we finished phandelver and my party had an interesting relationship with frank. They talked to frank and got him to be neutrel in their fight against glass staff as they were going to feed glass staff to him. This blew up in their faces when they lost in their fight against glassstaff (they gave him time to prepare and he used his scroll of fireball on them). When they tried to retreat frank stood in their way... the got frank to leave them alone by telling them where the prisoners were... Frank ate the little boy.
The awesome thing about frank is latter in the adventure they made their way back to the hideout and finally killed him off. But frank is not gone. when he died his blood scorched a symbol into the stone. The warlock of the party took a rest at the marking and received a vision of frank. Frank had been a mortal wizard in life and while in his nothic form he remembered none of his magic, but his spirit lived on. The warlock made a deal with him and allowed frank to survive in his own mind. and now "Frank" lives in him whispering eldritch secrets and deeper power...
My players just walked right past it, even as it tried to talk to them about personal trauma from their pasts that it should have had no way of knowing anything about.
