Seklos is the posthumous overarching protagonist of the Tales of Arcadia franchise. She is one of the overarching protagonists of 3Below, albeit being a posthumous character.

She is an ancient Akiridion celestial who sacrificed her own core to save Akiridion-5.


  • Mundicide prevention
  • Self-sacrifice



After Gaylen created the planet Akiridion-5, his power became too much and he attempted to destroy the planet. Seklos intervened to save the planet by sacrificing her own life core in her cannon and destroying Gaylen with it, leaving behind only his own core.


After General Morando claims Gaylen's Core himself and uses it to become bigger and more powerful, Aja, and Krel Tarron create a new version of Seklos' Cannon. Though the two intended to sacrifice their cores so their parents, King Fialkov and Queen Coranda, could live, the latter two intervened and sacrificing their own lives by placing their own cores into Seklos' Cannon. Thus, Aja and Krel Tarron aim the cannon at Morando and destroy him along with Gaylen's Core.


  • Seklos is one of the first two deities/celestials to appear in the Tales of Arcadia franchise, the other being Gaylen.
