Whisper woke up in a cell. Not remembering how they got there, in the depths of the hospital they couldn't grasp what happened all they knew was a strange rune on their arm itched and they felt a tingle in their fingers. Everyone that came to see them spoke of a Mist. That they could hear the fear in those words. A word they have learned to fear.... Mist. Oh so similar to air they think.
That aside there are few things they know about themselves, but they know their instincts. They will figure out what this itch is, why they were in a cell and how they even got to Underhaven in the first place.
