Year 1990, in a remote snowy village, a strange mountain appear out of thin air.

The villagers become panic, they think this is a sign of devil doing, some flee, but some decide to perform a ritual to banish the mountain out of their world.

20 men are chosen to go to the mountain to retrieve its "heart", and Koraqal is one of them.

He doesn't believe in demon, maybe this mountain is just a new part that people don't know about, we can never see a full mountain in these heavy fog.

But something happen, he realizes that all people inside his village have disappeared, that he can not go back.

Now, the only way is to go to the top of the mountain, together with other 19 men, and take the mountain heart.

Koraqal knows he can do this, a strange feeling that this is not the first time he climb the devil mountain.
