I got down to level 4 of Kernell's Hideout. I can't open the portcullis that leads out to the level. After rwading some information from a few sites, it appears that there is supposed to be a Troll Guard on level 3 who has the key. However, level 3 was jsut a small room with the enttances to levels 2 and 4, with nothing else present. Am I missing something?
