El descendiente de los anillos divinos

When darkness invades the city, zillions of human warriors come into being, but Aiden isn't one of them.
One day, he comes across a mysterious ring and is sent into the Orc Realm where humans are forbidden, by a treaty.
He magically survives his execution, lifts the Orc Tribe's sacred hammer, and becomes the tribe leader.
Just then, he is transported back to his original reality.
