Any character may detain another character. A Player's movement OOG should never actually be impeded or restricted by a room, door, or binding.
Locked Room - Never really lock a door, use a Lock prop. A person in a Locked room may leave after 30 unguarded minutes assuming that ‘there was a loose bar or open window’. The presence of a guard negates this. Climbing out windows, breaking props, ignoring Locks (without an IG ability) and playing other characters is not permitted.
Bindings - Wrist bindings (rope, cuffs, etc.) prevents the character from using their hands for 5 minutes. The player holds the bindings in their hands. The duration pauses if another character holds the bindings, or resets if another character ‘tightens’ them.
