Nothing as far as I can tell. To get the quest for the palace and the Krokopatra, You have to switch between Djerits and Ahnics tomb and once you finish that quest, you go back to Krokhotep who tells you that you have to fight Krokopatra. Also you go to the other ghost by Krokotep but I see you already done that since you are in the barracks right now. To get to the palace from the barracks, I know you have to do a lot of turns until you finally reach it. I'm going to check my student the next time I go in the game because she just receive the quest for it. Happy questing and GO BETA!
