Moonbeam is an unicorn fond of humans with troubled hearts.

I wanted an assistant with a fantasy feel. Moonbeam is patient with you, but will also call you on your bullshit when needed. I guess they also work on the other end of healing characters, this one being the healer and not the hurt one. The setting is not specified to be either medieval or modern, so you can specify as you want. They got a background of their own too if you want to know them too. Enjoy.
