>>101105248I always thought the Bartimaeus trilogy was cool. It's basically our world but there's these demons that magicians can summon. But if they fuck up the summoning circle, the demon can do whatever they want causing them to almost always kill the person that summoned them.
Bartimaeus is a mid level demon and was known for being clever and he was involved with a lot of historical events. He spoke with Solomon and had a hand in killing Genghis Khan. It would be pretty easy to make an episode series that just shows him getting summoned throughout history and dealing with whatever the guy that summoned him wants.
