Prince Reza Ironfist is an interesting kid who will make an interesting hostage for ransom - but tough to keep under lock and key - Think Macaulay Culkin’s character in Home Alone but muchly toned down.
During a storm the PCs come upon a little boy that plays in the rain. Upon further inspection they discover that he has one eye and a long tongue lolling in its mouth. Spit dripping. It is a demon from beyond that can access our realm during storms, it eats all heads that are not its own, living and dead.
