Shards of Oblivion

In a world, two spieces live together peacefully, humans and Erystals, elemental creatures with humanoid features, where the only organ inside them it's a crystal, holding they're thoughts, emotions and life force.

Two friends bonded by an unrivalled friendship, fighting for that peace broken by an evil soul, aiming to conquer every land and emptying it of everything that lives...for power and oppression.
