Karst was a haunted town where imps and undead creatures lurked in. The Estian army cleared away a number of imps which were running around the town, and shot down some Nightwing imps which attacked from the sky. The landscape of Karst had been badly damaged by those imps, which the army unfroze a forest the imp resided, and bursted some imps near the houses which were ignited. After rescueing the people in houses, the army came to the wishing well to deal with ghosts haunting there. A group of Abtu-Kahn worshippers were found to worship their gods, which were then shooed as well.
