Actually, this works out better then expected. If all the armed warrior dwarves are down in the lower mines, they are all going to die when the gas attack hits... as will Clotho's minions and quite possibly Xallihion as well. I'm not sure how the Squidhead is going to get out of this alive since he is based somewhere in the lower mines without striking a deal with Clotho to give him a fast way out.
