Crown of Horns
Famous evil artifact associated with Myrkul
This Netherese artifact looks like a rough silver crown covered in horns of various lengths, though it can change its shape based upon the needs of its chosen wearer. It seems to be able to create undead at will.
What is commonly known about the Crown of Horns is that it was utilized by the former God of Death, Myrkul. as a receptacle for his divine essence after he was killed in Waterdeep. It is still in the world creating evil and raising undead, recently taken from the head of the so-called Snake God.
Who wore the crown between the death of Myrkul and its eventual time on the head of the Snake God is unknown, but it is currently in the uncomfortable hands of the PCs.
