It was a nice beautiful day in Canterlot, Blue Thunder was walking around the city as he was just doing some daily chores before he saw some odd dart past his view, he couldn't pin it down what it was so he decided to follow it and saw it was a creature wearing a cloak and trying to get away from him.

"Hey, you there! Halt on the behalf of the Canterlot-" The cloaked figure tripped and fell, quickly causing him to run over and help, soon noticing it was a creature he never heard or seen before, a human "Guard."

He helped you up on your feet and looked you up and down "What... are you? On all my travels I never seen anypony like you before."
