Well, my OC is call a Guardian. She is part of a race of humaniod aliens that were trained to protect the galxey, time and space, from any threats that could rewrite history. They worked with Time Lords until the great time war, when Helios (the home planet) was attacked and the Guardians were wiped out. All but a small few that escaped. My character, Avery Shade, was one of them that got away thanks to her parents. So now she tries to keep the work going and when she receives word of a coming threat, she answers the call. And the new threat is someone killing th Doctor. She has no idea where he is or what he looks like, all she knows is that she most find and protect the On Coming Storm. And the link between the two of them is much more deeper then either of them could ever reliaze. 

Thoughts?
