Ben Valis

Q.C., Mythic and Demonica, i.e. summoned demons. Originally lived 1843-1878 but through some sort of magic was able to achieve long life, although in the 50s/60s he became more weird and stilted, possibly as a result of magic done, possibly as a result of long life. His son died after Ben blocked his marriage, his goal was to resurrect him (by killing a bunch of other boys, or making deals with the True Fae, he had a bunch of plans) so they could happily live the lives of demon summoning magicians. Sadly he was slotted one Friday evening by a pack of angry werewolves.

He spent some time in Washington D.C. but had to leave in 1943 because MagiPol found out he'd been murdering people. He came back to the UK in the 50s or 60s with his alchemist friend David Vasiry

Largely the villain behind Season One and more was found out and he died at the end of Season Two.
