Ok heres the situation and recap of last session. My group went into the Laborers Quarters (First AP) and went into the room with the slabs. They fought the Beetle and left the room with half the party exausted and in need of rest. Thing is they want to rest at the bottom area where they enter (cant remember what section number it is off the top of my head) anyway they havent encounter the swarm and bombardier beetle in the other room. If they do rest what do you think the chances are that these things become aware of their presence? Should I be an "evil" DM and send these things after them or should I let them rest? What would you do?
