Solus Prime was at the very front of the war against Unicron. She was there when Megatronus turned to Unicron, and became The Fallen. She has been in hiding for millennia, but has deemed it is time to reveal herself to more than just her young, AllSpark filled charge, Caitlin. Of course, teaching a college astronomy course wasn't the glorious return she imagined. ((Caitlin Lennox does not belong to me, she is the OC of my wonderful friend @DontTripOnYourMind )) ((I also don't own any of the Transformers characters, those are Hasbro's.))
