Sebak

Sebak was one of Naeem's first followers leading up to the slaughter on the AMF base. Throughout his attempts to bring his brother Abasi to their side, he found himself conflicted over wanting to return to the old days, and wanting to save his brother. After all he knew that Abasi would be slaughtered with the rest of the traitors. (and also knew that Naeem had no plan of waiting for William Sterling to fulfill their prophecy by taking Ammon's place)

During the attack, Sebak sees that his brother refuses to fight any longer and is then stabbed by Naeem. After Naeem and the other rogue followers leave, Sebak stays with his dying brother, having regretted ever choosing Naeem's side in the first place. He also realizes that he too is done with the killing.

Shortly after, he is seen throwing his dagger to the ground, refusing to be a part of the slaughter any longer. Naeem is enraged and declares Sebak a traitor; in which he accepts. However, it is Dendera who convinces Sebak that he can do right by the humans and join their side. She asks him if he would rather die a traitor or a hero; he agrees he would rather die as a hero.

After Abraham is stabbed by another warrior, Sebak shows up and stabs that warrior in the back in attempt to prove he is on the AMF's side. Afterwards, both him and Lynne carry Abraham off the infirmary, and a blood transfusion is carried out using only Lynne's blood "As Tjatey blood isn't compatible," she states.

In Atlantech Days of Darkness, it has been a month since the attack and Sebak now works at Atlantech; taking Onuris's place. He and Dendera also affirm their feelings for one another and begin a relationship. It reminds Sebak of one of the last conversations he had with Abasi almost a week before the attack. Abasi had asked Sebak why he hadn't found a life partner for himself. Sebak didn't know the answer then, but later on he is positive that he's found such a partner in Dendera.
