Of Greed & Hunger (Tommyinnit)

It looked like it was starving.

The way the creature advanced was unnatural, fluid and then stuttering a second later as if its bones fell into place repeatedly. It moved like something trying to imitate a human but that didn't understand how the anatomy of one worked. Jerking a long limb forward it then painstakingly slowly brushed its long black claws along the sand.

This was a Mammon.

Or;

Tommy gets sacrificed to a Demon but instead of eating him, it takes him home.
