Thank you, ravells!
Now that I've begun my fight with Illustrator (aka trying to adjust to this horrible interface), at least I managed to scan and edit the file so the contrast sticks out more. This picture is the version my gamers will see (lacking all the secret doors, hallways, stairs etc). Of course I'll make the handout a bit prettier when they get it, but I'm sure they'll take until October to get there, so plenty of time to finish other stuff first
