Night Guardian is a guard who has been given the job to guard the most wanted criminal/creature in Equestria.

The creature, unknown to all ponies named Jason Sanders, a regular human from Wollongong in Australia, tells Night the story of how he ended up in his cell, how he became the most wanted criminal of all, and even how he ended up in Equestria...

This was the first fan fiction I have ever come up with and have been brainstorming this story and it has been stuck in my mind for YEARS. Hope you enjoy it!
