This addition comes from report 1713 from the last liaison round.

The security ministry now has access to a new command section: CITY SIGILS. This allows them to set up sigil layouts, similar to how guard layouts work, and easily replace missing sigils.

These sigils are drawn from the quartermaster, and the Trade ministry can manipulate monolith, cube, flame and key sigils just any regular comm. That means they can sell them and buy them from the city's commodity shop, as well as consign them to the quartermaster for Security's use.

Command overview:
CITY SIGILS VIEW
View the sigil layout for current room.

CITY SIGILS SET <MONOLITH/CUBE/KEY> [room]

CITY SIGILS UNSET <MONOLITH/CUBE/KEY> [room]
Does the opposite of set.

CITY SIGILS LIST
List which rooms have a sigil layout.

CITY SIGILS LIST MISSING

CITY SIGILS LIST UNASSIGNED

CITY SIGILS REPLACE
