Rhea was able to kill Nemesis and reclaim both Sothis's Crest Stone and the Sword of the Creator from him. In the process, she founded the Adrestian Empire and the Church of Seiros, the latter devoted to the worship of Sothis. Rhea, the only survivor of the massacre, enraged and grief-stricken by the slaughter of her people and the theft of her mother, took on the name of Seiros and waged war against the King of Liberation to avenge her family and reclaim Sothis's remains. Nemesis subsequently slaughtered many of the remaining Nabateans at Zanado using the sword, and Those Who Slither in the Dark used their blood and bones to create Crests and Heroes' Relics for at least eleven of Nemesis's allies. Using her blood, they planted her Crest of Flames into Nemesis, while also fashioning her bones using their technology to create the Sword of the Creator, a sword of unparalleled power when used in tandem with the Crest of Flames. They convinced a lowly bandit, Nemesis, to raid the Holy Tomb and steal Sothis's remains. Needing to recover, she rested in the Holy Tomb, while the remaining Agarthans went underground.Ī secret underground civilization composed of the remnants of Agartha, known as Those Who Slither in the Dark, used Sothis's vulnerability to their advantage. One of her final children, Rhea, was born just as she finished restoring Fódlan. The war resulted in massive bloodshed and Sothis exhausting her power to restore the land, taking place over centuries. Her blessings were soon abused by the people of Fódlan, more specifically the people of a civilization named Agartha, leading to countless, pointless wars and even attempted to kill Sothis herself, seeing themselves as gods. Her descendants would help pave a future for Fódlan of great technological and societal advancement. Her blood was used to create a race of beings called the Nabateans, also known as the Children of the Goddess. She descended upon Fódlan from a faraway place, often theorized to be the Blue Sea Star, several thousand years in the past and took on a human form to live among the people. In truth, Sothis is the consciousness of the Goddess, thus is in many ways the Goddess herself.
