Alliance of the Sacred Suns is a sci-fi grand-strategy RPG that begins with your coronation as the head of an interstellar Empire, and ends with your demise. Manage feuding noble houses and the schemes of would-be usurpers as you try to revive the glory of an Empire on the brink of collapse.
Alliance of the Sacred Suns
SteamIn the far future, the last of humanity's great Empires sits on the brink of collapse. The great noble houses fight amongst themselves as they seek their own enrichment while the people of the Empire struggle to make ends meet. Amidst all the political tension, your predecessor has passed away, and you have ascended to the throne.

In Alliance of the Sacred Suns, you play as the young Emperor of an interstellar Empire riddled with social, political, and economic issues. As a blend of grand-strategy and RPG, you will make decisions that influence the future of the realm while managing your court, your relationships with the great nobles of the Empire, and your own well-being.


As a young Emperor taking the throne, you have your whole life ahead of you to return the realm to its once-glorious state. Be wary of separatists who seek to undermine you, and those who do not respect your title. Many are willing to bring a quick end to your reign by any means necessary to further their own agendas.


The Empire has been in decline for generations as you take the throne - the formation of the Great Houses and their growing strength has come at the expense of the throne's centralized authority. The nobles know where they stand in this hierarchy, and though there is a degree of respect for your office, many will use what they have as leverage against their Emperor.


Whether interacting with leaders of the Great Houses, your own family, or citizens of the Empire, you will have many opportunities to define the kind of sovereign you are.


Your Empire cannot remain stagnant, even as it decays from the inside. You must project strength in a variety of ways, for vultures are always in the skies above.
