Summoning a daemon to the mortal plane requires a donation of some kind, preferably of human origin. Many daemons demand specific payments for their service, but generally the service depends on the value of the donation.
In hell (where he is known as J͖̬̙͎͓͎∃̶̦̮̟R҉̣͕̖G̗̭͕̪̯̞͚͝J̭̱L̦̞͚T̡̜H̭̣̫̯̫͈͡Ü̗̝͍͖̠̤), Jiles isn't hugely notable but still well respected as a skilled tormentor. His specializes in confusion and fear of the unknown, and requires payment in a similar vein.
No one is really sure what this payment is, including himself, so until the house party he had never been on Earth before.

When he was called, he was immediately confronted with myriads of new sounds and smells and auras. Experiencing Earth for the first time is exciting for all daemons, but for Jiles it was a sensory theme park. Since the abstract is his element, his first summoning has turned into an extended field trip full of drugs, alcohol and goat blood.

H'es generally friendly but unnerving, especially when drunk. He gets pretty cranky when he's sober since sober generally means hungover. Cranky also generally means terrifying and currently if not soon to be covered in blood. He does various things for fun until he gets bored, he discovered films and decided he runs a small movie theatre now. The reviews are pretty complimentary, although there are mixed opinions on the décor.
