Oilacbrothers application.

It will be up to you, Mary Gilbert, the famous botanist and guardian of Fern Flower, to once more enter the magical world of eastern European deities, ancient beliefs, and mythical lands when a visit to your brother that appears to be uneventful turns into a hotbed of conflict between humans and Clouders.
Set off to the other side of the rainbow with a house spirit named Aitvar, where your brother is being held captive by an evil sorcerer and a flying city floats in the clouds. Renew the long-standing pact between humans and Clouders by saving him. Will your shrewdness and inventiveness be sufficient to defeat the evil Zmeys in the sorcerer's service and demonstrate your worth to Perun, the thunder god? Will you be able to save the planet before the ocean floods it?
