This is my first rendition of Mortmercaton's "brother," Nekukakos.
His name roughly translates as "the putrid dead"
He is a death demon with the Domain of:
Death caused by:
Considering his wide range he is one of the strongest of the death demons and possibly one of the most ancient. However, he is always distracted by his "studies" and tends to ignore his "siblings'" dealings along with the mortal realm in general for centuries at a time. He slowly rots away and will become a complete skeleton. However, he has a ritual by which he renews the flesh on his physical body. He is the only death demon other than Mortmercaton to take on a physical shell.
