I've got more to write about the use of the signs, and I'm gonna work out specifics for the different mage/creature specific signs, but these are the ones I've come up with so far. If someone thinks of any other signs that would be useful let me know and I can add them.

[b]Escape Route:[/b] This doorway/hatch/etc leads out of the city, city district or at the very least beyond the bounds that the guards in the area are likely to search in.
[b]Fence:[/b] A fence lives and/or conducts business here. This sign also marks the place as protected.
[b]Fence variant:[/b] A fence lives and/or conducts business here, and is likely to accept “hot” goods. This sign also marks the place as protected.
[b]Protected[/b]: Any building marked with this sign is under the protection of some part of the criminal and/or mage underground. This might mean that they’re paying protection money to some part of the underground, but it might also mean that it’s the home of the head of a crime family. Steal or make trouble here, and finding a fence will be the least of your troubles.
[b]Safe-house:[/b] This place should be safe to hide out in if you need to lay low.
