The many faceless priests in identical robes throw some generic responses at you (written on parchment and wrapped around rocks). Roll against your dexterity or take d6 damage from parchment wrapped rocks. That said, even though these guys are sniggering at you in their Mighty Fortress you are in the right place.

How do you go about getting the Mighty Fortress? Ask lots of times and tell all of your friends to ask if you can get in too and also ask people you don't even know to ask for you as well and also ask them to ask people they know? A wizard might have given you a scroll that lets you ignore walls - I don't know when but he did and maybe you could use that? You could also have some magic exploding acorns that you got as a reward for some mighty deed that you maybe did that you could use to blow the doors off the mighty fortress. Or if you visited the Big Library of Steamovia there is another option.
