Because of Ereshkigal's Curse, the ice city at the Kurngalfberg has been covered by a sheet of ice for 700 years. Kistenian, a Daeva of the Flame, was instructed to bring the city back to life. But he needed Kasadrasil's help to thaw the city. He said that the city can only be saved if the Elim Kasadrasil awakens. So he asked you to awaken Kasadrasil with the help of the essences of Anorama, Triminos and Etun. When you applied the essences of the Elim, Kasadrasil slowly awoke. When Kistenian learned about it, he was delighted and said that the ice on the Kurngalfberg could now be thawed with Kasadrasil's help.
