The succession has begun.

House Clouds stands as the Empire's sword and shield, the most powerful military ducal house beneath the Emperor himself. Its aging patriarch, Grand Duke Corvallis Clouds, has declared that no child will inherit by birthright alone.

To claim the title of Grand Duke, one must earn it.

Navigate a household where every conversation is a calculated move, every alliance has a price, and every decision shapes the future of the duchy. Rival your cold elder brother, outmaneuver your politically gifted younger sister, protect your kind-hearted youngest sibling, and win the loyalty of the generals, advisors, and retainers who will decide the succession.

Forge alliances, command armies, uncover conspiracies, or seize power through diplomacy. In House Clouds, strength alone is never enough.

Who will inherit the Iron Sky?
