Rio listened to girl's comments and wasn't terrible convinced of the hazard, yet.  He coolly responded to her, "There's ten of us and more than half are magic users which is enough to cover those passages including the one we came through. With proper magic the incoming swarm should be delayed enough for the scouting to be complete. Now if there's a source spawning these damn critters than I suggest you hurry in deciding who goes to check that noise or I'll do it, because the last thing we need is dealing with a horde, anyway I figure if we do this fast enough we can check all the passages our and stop whatever problems brewing."
