[Rhys had thought he'd gotten used to all the little changes the castle liked to enact, having been female, younger, older ... but no, this was entirely new. He didn't even recognize what he was. All he knew was that he'd woken on a bed he'd no longer fit on, promptly slammed his massive horns into the ceiling as he stood up, and then sent students scattering in all directions screaming when he'd emerged out into the hallway, heading toward his House to check on his children. He didn't even have his wand, and was apparently incapable of performing even simple wandless spells. How frustrating.

From the odd forms glimpsed here and there, it's clear this has happened to more than one person (as usual), but no one will stay within arm's reach long enough to talk to him.]
