I Like Maps of Mystery, I've managed to use the dwarven mine from the dungeon issue with strike on the rabid dawn 6 times now with the same group of players and i reckon i can still wring a couple more goes out of it, the reason it's so useful is because it is just a nice expansive floorplan that i had to do nothing but populate it and populate it i did, with Ilithids, Drow, Duergar, Pirates, Cannibal Cultists, Pirates, Half Orcs, Githyanki, Pirates, Goblins, Pirates and a Half Drow Half Githyanki Cleric, It got a tad hectic and involved a lot of novel uses for sunrods
