The heart that melt the ocean. Morrigan B.

Once upon a time, the island of Koa’Koa was a paradise, but everything changed on the day of the disappearance of my grandfather. After that, the world was constrained by eternal winter, and the frozen ocean cut us off from spirits that our people were carefully protecting from the beginning of the time.

I was born much later than tragic events, but it was I who had a chance to go on a dangerous journey and find out, What happened thirty years ago.

If I solve this riddle, I can melt many years of ice and return home. If I fail to fail... it can cost me life.
