Raiken's Training

Inside the large cave, on the side of a snowy mountain. There was a whole distinct environment inside. 

The mouth of the cave leads to the evergreen and spring-filled habitat that is literally like heaven in the snowy region. It was due to the presence of an underground hot spring inside the cave area that resulted in the formation of this mini heaven. 

It was the lair of Goke, now the place or home of Sachem, Raiken. He had taken over this mini paradise cave of Goke when he moved here. He alone lives here, perfecting his arts, improving his magic mastery because only by shrill luck he was able to survive that fight with Goke.

Even now remembering that fight gives him goosebumps. He was this close to death in that battle and what can you say by a twist of fate or mockery of fate on Goke. He lost his life by chance otherwise the person to die that day would be definitely him.
