A system for add a easy time to the DM and builders for add Innkeepers avoiding the problem when a Player it's resting on his room another player get the same key and get on the room too.
This system let you have custom key for doors, where only a player can get a key, to at least the previous player have the key by a custom amount of time (changes of locks) and for those players who like ask keys and never get back will need to pay a fee for this bad habit.
Very friendly and give flexibility as how save the info (global, campaign or local vars).
This rar have the erf with the system - inside of the erf are a readme with a complete manual -, and second erf with two simple scripts for close doors (but probably you already have some of those on your own module) and a module with two examples of how put the system.
