When humans come to Equestria, it changes them into ponies.

Yet another human has found their way to Equestria. This one however was captured, a good idea as far as anyone can tell. He appeared in a mask, in dark clothes, and with strange weapons strapped to every part of his body. No hero has that color scheme or presence about them.

He gave up willingling, and was subjected to a magical slumber, in which Luna interrogates him to find out if their hunch was right. She wasn't ready for what the human would bring to the table of the mind though.
