High above an endless sea of thunderous clouds, several floating island is drifting through the heavens. This is sustained by a power magical artifact known as Aetherstone. Aetherstone, a magical artifact that bends the gravity allowing the island to float in the sky. For generations, life in the sky has flourished, untouched by the chaos hidden beneath the roaring clouds known as the Stormveil — a place of lightning, mystery, and death.However, they have discovered that the power of the Aetherstone is fading. The islands begin to tremble and fall into the storm below. The High Council of Elyndra, terrified that the entire Sky Kingdom may soon collapse, gathers its finest minds — scholars, mages, and inventors — to find a way to restore the world’s balance.During their research, they unearth an ancient text buried beneath the capital. It tells of the "Heart of the Sky", a forgotten source of power that could rekindle the dying Aether. But the final passage reveals a forbidden truth: the answers lie beneath the Stormveil, in the lost world below the clouds.With no other choice, the Council enacts a kingdom-wide decree: Every household must offer one family member to be trained as a "Descendant" — explorers chosen to brave the Stormveil, recover the Heart, and restore the skies.In a world built upon clouds and secrets, one descent will decide whether the sky remains… or falls.

How would you react if you saw your family slaughtered right before your eyes? What expression would cross your face? What thoughts would race through your mind?
