The night before the final battle, Nameless fell into a great sleep unlike any he had experienced in life. In this sleep, as in nightly meditation, he searched through a dark mist. This plane was a barrier to the answers he sought: who was he before given purpose by Osiris?
Suddenly, the floor yawned beneath him, revealing a gateway to his past. He fell began to fall, and fall, and fall, and as he passed through layer after layer, truth was finally revealed to him. He had had not just one life before his service to Osiris: he had had many, and each of them was in service of Set, the great and wicked Undoer. In each of these lives, he had reached terrible ends and had been mercilessly brought back to service to carry out evil means.
He awoke in the morning with a clarity he had been unable to attain in centuries. He contained a hundred horrible lives, a thousand horrible deeds, and one irredeemable mistake. In ancient Eqb'sh, a man named Haurun and his wife were unable to conceive a child. After all other options were exhausted and holy offerings ignored, Haurun made a deal with a mysterious Magi. Haurun did not realize that it would bind him to an infernal contract with the Lord of Evil himself.
His first death was at the last banishment of Set, and many times thereafter did he perish in wicked pursuits of Set's design. Osiris arrested him from this cycle, and in this new life Osiris shrouded these memories, protecting Haurun from his haunted past. The memories eventually clawed their way through, and now, Haurun had renewed resolve that he would end Set's ploy for conquest. Osiris's judgement be upon him!
During the final battle, Haurun was blinded by vengeance and came very close to death once again. He faced an arch priestess of Set alone, one they called Fahtima, and she cast him through the very nine levels of Hell. Haurun once again relived the torment of his enslavement, and he faced the possibility of perishing without fulfilling his purpose.
As he finally laid eyes on Set, his once-master, he felt an inescapable dread; but he did not face Set alone. He was bolstered by heroes, each with their own reason to oppose the arch devil: to save their home, to save their family, to save their friends, to save the material plane.
As Haurun fought, he accessed power he never realized he had--power bestowed by Osiris. And as he spoke the name of his enslaver through the silver circlet, by speaking against his oppressor did he remove his power over him. Darkness gave way to brilliant light, and its radiance began to chip away at Set's great deception.
In a final assault, having exhausted the last of his defenses, the heroes bested Set and banished him to his prison for another thousand years. Haurun bequeathed the "Voice of the Par'aa" to the druid Nak'Cue, whose glade now took the responsibility to keep Set in banishment at the next millennium. Haurun promised to send a priest from his home in Eqb'sh to establish a temple to Osiris there in the glade. As the heroes parted ways and said their goodbyes, most of the realm was unaware of what had happened that day.
