I know it was something @Accipiter mentioned in passing when the plaza was Halloween-ified, but I though I’d put it here on the forum as well.
The idea is that like characters, rooms could have profiles that room owners can switch between for things like special event descriptions/pictures (like for holidays, seasons, and such).
It wouldn’t need to be too extensive in my opinion. Just the description and image, nothing to change with the exits, areas, or any other room traits.
