Nobura is a forgotten planet shrouded in mystery. The legend is that a cosmic being sacrificed his divine essence to breathe life into the desolate lands. Etherstones formed the planet's biomes and connected all living things to nature.

Yet the lingering threat of the Vacuous, a parasitic force born from the depths of Nobura, poses a challenge to life on the surface, weaving a tale of divine sacrifice. Nobura has always been part of a paradoxical cycle of life and death, where the forces of creation and destruction dance in an eternal cosmic battle.

In Etherstone, players embody faction leaders who join forces to prevent impending extinction. They strive to gain the most victory points through various actions, such as summoning cards, overcoming threats, and using their skills as effectively as possible.
