Skulla's not exactly from around here. Not too long ago, there was an accident, a rift, and another Salamander, although slightly different. the newcomer, who calls himself Skullamander, has memories of a world so very familiar to the one he's in. Almost identical people, almost identical places, almost identical histories. Once a few key differences were found, a medical exam was carried out.
Dialogue is from the Rockefeller Tree Tragedy.
As a note, Skulla's organs actually are mirrored.
