great fun, i tried doing 4a as some secret temple with pits to keep sacrifice victims in and rooms for cultists (who were on the keep's staff at some point in the Castle's history) - unfortunately for them they dug further to expand the temples and found a cavern with a pool of weirdness that mutated them into zombie ratmen over time. lots of rat tunnels - y'aint wearing plate there comfortably unless yr a halfling, maybe. Would do more but I'm gonna be away from the computer - drat
(oops - top centre-right -where 2 rat-tunnels meet in a plain floor block -should be a rathole)
