Zeydaan had finished her latest solo adventure- exhausted at the end, barely disconnecting her cloak before falling onto bed and closing the portal. Unfortunately, her cloak got caught in the door- its magical potency preventing it from being bisected as the portal closed.
Not even noticing the fact that it was left there overnight and let dimensional energy seep into the fabric- or more importantly, dimensional energy from other Zeydaans.
When Lenora offered to help Zeydaan find her cloak for a due wash, she weren't aware either. Noticing it suspended in the air by nothing- ripping it out and reopening the portal- energy surging through Lenora at an unprecedented rate- overwhelming her in a similar manner to how Zeydaan would typically transform from the same energy.
The cloak also fulfilling its purpose, recognising its master and forming the rest of the outfit promptly- Lenora not entirely consumed in the transformation- seeing this as more of an opportunity than anything. She had access to Zeydaan's powers and thanks to all that energy she seemed to have borrowed. And if the original Zeydaan was none the wiser- who said she couldn't give it a spin. After all, Zey was so irresponsible to leave all that energy lying around.
