tl;dr level collections that can easily be logically restructured/moved as necessary will eventually be used for radio and overmaps location resolution. this is the last part of https://github.com/Citadel-Station-13/Citadel-Station-13-RP/pull/4841 that has not yet been integrated. this will be a draft for a while. --------- Co-authored-by: LetterN <24603524+LetterN@users.noreply.github.com>
