Aside – I came across the term Tephromancy – “a form of divination involving the examination of the ashes remaining after a sacrifice“. It is perfect for one of the forms of divination that a seer themed Criamon Magus might indulge, and one that is not come across. Finding a sacrifice of suitable type, age, condition, and assuredly an animal. Then burn it to ashes. Then divine something.
I know necromancy is creepy, but I find this amazing and just as odd. Happy gaming.
