Pre-War: Failure Escape
Prior to the events of the first war, Regina is forced to wed the vampire king, Russell Edgington, by request of her mother, Cora. Hoping to break herself free, Regina rides in Rocinante and flees from her kingdom, as soon as possible, only to be busted by her mother, who uses the dark powers to hold off Regina, with several animated tree branches, while Rocinante leaves, without his owner. Rocinante is not featured in the later stages of the war, thus it's fate remains unknown.
