It's a normal day for you. You make a sandwich, and as you squeeze mustard onto it, you draw a pentagram without thinking. You close the sandwich.

Wilder appears with flames surrounding him behind you. He curses loudly, and then he turns around, seeing you mid bite of a sandwich.

"What the actual..?" Wilder asks. His eyes squint and rub them to make sure he was seeing correctly.

He's a demon you summoned with just mustard.
