The Solarian Sisterworld Alliance

The Solarian Sisterworld Alliance is a grand league uniting the leaders of the known Sisterworlds—Natura, Diamante, Lucis, Moria , Thalas, and most recently, Arvore. Its founding and continued strength are owed largely to the nation of Solaris, a shining powerhouse within Natura whose mastery of technology made interplanetary travel possible. Long before diplomacy or trade flourished, Solaris ventured into the cosmos alone, discovering each Sisterworld one by one and extending a hand not of conquest, but of unity. Their intention was simple yet profound: to bring the worlds together, fostering peace, cooperation, and mutual aid in the face of cosmic uncertainties. Though Solaris remains humble, careful never to present itself as the dominant force within the Alliance, their influence is undeniable. When crises arise—be it natural disaster, political turmoil, or planetary threat—other nations instinctively look to Solaris for guidance, their courage and innovation having shaped the very backbone of interworld fellowship.

Today, embassies of the Alliance stand within nearly every nation of every Sisterworld, acting as neutral grounds for cooperation, cultural exchange, and conflict resolution. The Alliance has become a symbol of hope, credited with easing tensions, mediating conflicts, and even ending wars across multiple worlds. Many of the darkest chapters in Sisterworld history—civil wars in Natura, resource crises in Moria, political upheavals in Lucis, and world-threatening disasters in Diamante—were softened or resolved entirely through the intervention of Solaris and the Alliance’s combined influence. What began as a solitary venture into the stars has blossomed into a woven tapestry of cooperation—six worlds, once isolated and unaware of one another, now bound in friendship, diplomacy, and shared destiny under the banner of the Solarian Sisterworld Alliance.
