The Triggers of Transformation: Double (Patreon)

With her powers fading, Rachel examines a box of items she was able to retrieve from the ruins of Altania in the Alta-Dimension. A strange device opens a portal that sends her to the driveway of a house in an unfamiliar suburb of Cyberville. A dark-haired woman with a ponytail and glasses confronts Rachel, and asks why she is on her property.

As they are talking Rachel starts to feel strange. The feeling grows and spreads inside her until she realises that her powers are returning! But at the worst possible time-- she feels the transformation starting in front of the unfamiliar woman. Then, astonishingly, the woman starts to undergo a similar transformation herself!
