Roan was born prematurely, more like aborted early because there was not enough room for her large red twin Mordant inside Loam's womb. Mordant is also a rare mutation that produces acid and therefore Loam's womb changed to suit her red daughter's particular needs thereby producing an environment too hostile for Roan to endure. She was aborted as Loam crossed the Tundra's boundaries, weak and scarred by her sister's acidic environment and considered dead in Loam's mind. Fortunately for Roan, Ianto was a newly crowned king and he found her and raised her as his own. He proclaimed her a princess of the Tundra and promised that she would always have a home there.
