(Happy Birthday!) Bandit: It's sorta like a room which appears when you require something, hence the name. For example if you were running away from a teacher, it could be a storage room. Etc
Bandit: -Winces- Not sure what it'll look like inside. -Pushes open the door completely- ~It reveals a small-ish room containing a comfy sofa, 1 red armchair, a small coffee table, a fountain in the corner of the room and a few other home like things.~
Bandit: -Looks around curiously- Last time I was here it was a small bare room for practicing spells in..
