Piperka

The story of five kids who stumble upon another world, following a mysterious medallion holding a magical guardian. They discover magic marked by its array of colors, and creatures unlike what they had ever heard of. They are asked to help free the trapped magical guardians but are met by barriers they never meant to meet; like a band of unicorns living under a waterfall- broken by war and paranoid to the change in their isolation, a golem forged in peace and used for cruelty, a war fought with storms, a monstrous race of cannibals, and the strange king who leads them.

While things may seem dark, they stay positive and foolhardy in their task to do great things.
