Sai Aguilar

Sai Aguilar, fabled leader of The Eagle's March, stands immortalized in history as the founder of Solaris — the kingdom that would one day rise to unite Natura and the Sisterworlds. Over four thousand years ago, Sai led his band of hardened mercenaries across the warring lands of the age, carving a path not for conquest, but for peace through strength. His most defining moment came with the defeat of the oppressive The Cicadean Empire, a militarized force that once reigned over the world with cruelty and arcane might.

At the heart of this conflict lay The Miraculum Crystal— a powerful, mysterious relic said to amplify one’s innermost desires. Sai succeeded in taming the crystal’s chaotic energies, forging it into a symbol of unity rather than domination. But the cost was personal. Fighting by his side had been his own brother, Mahz-Tul, whose soul succumbed to the crystal’s corruption. Torn between loyalty and duty, Sai was forced to confront Mahz-Tul in battle, a clash that nearly shattered them both.

Though history reveres him as Sai, the name he was born with was Sai-tul, a truth carefully erased from most records to distance the founder from his fallen brother. The whitewashing of this name served as a quiet political decision by later monarchs — a way to preserve the myth while burying the pain.

After establishing Solaris atop the ashes of the old world, Sai was approached by the brilliant and elusive Stardust Fairy, Xiraiin Trinnial — a scholar who had spent her life uncovering ancient truths and forbidden technologies. Offering him a trove of knowledge beyond the age, Xiraiin shared the secrets of celestial magic and emerging science, sparking a technological and cultural renaissance that elevated Solaris from a kingdom to a beacon of progress. With this newfound advancement, Sai's dream of unifying the world through vision, discipline, and enlightenment was no longer fantasy — it became legacy.
