Sarevok was saved from death at a very young age. A group of Bhaalist cult members gathered several Bhaalspawn children together at their temple in the Forest of Wyrms, and prepared to sacrifice them to the Lord of Murder. A group of Harpers assaulted the temple and saved the children from a grim death. While some of the Bhaalspawn were rescued or adopted, Sarevok was unfortunately left behind. He grew up as an urchin in the streets until he was adopted as Sarevok Anchev by Richtar, the Arm of the Iron Throne. Richtar used the alias of Rieltar Anchev while acting as Sarevok's father and establishing the Baldurian branch of the organization. When Sarevok was just a child, Rieltar had his foster mother strangled with a garrote in front of him. This tragedy greatly troubled the young Sarevok. Revelation of Heritage Sarevok the Bhaalspawn Like other Bhaalspawn, Sarevok had vivid dreams of destruction and mayhem that were accompanied by apparent messages from Bhaal himself. At some point he confronted a priest of Bhaal about his dreams but gleaned nothing useful. Consequently he slew the Bhaalist. In the Year of the Sword, 1365 DR, Sarevok traveled from Ordulin to the Sword Coast alongside his adoptive father Rieltar, in order to expand the Iron Throne's operations in Baldur's Gate, and the Western Heartlands. Sarevok used this opportunity to begin researching the prophecy of Alaundo related to Bhaal, and his relevance therein. He came to understand that he was indeed one of the Bhaalspawn. After reading the line: "deaths they bring shall awaken the father, and through them he will rise", Sarevok believed he had to incite killing on a grand scale in order to assume Bhaal's portfolio. While in Candlekeep he encountered the monk Gorion and his ward Sora. He quickly came to realize that Sora was indeed a Bhaalspawn like himself. After he gained some sense about his divine heritage, Sarevok studied under Winski Perorate to learn more about the dark arts associated with Bhaal. With the aid of his new mentor he came to understand that a grand slaughter of massive scale was needed for his ascension. Cultivating Influence During that same year of 1365 DR, Sarevok assisted his foster father with his grand scheme that would to bring great wealth and influence to the Iron Throne. A group led by Rieltar's subordinate Mulahey would begin sabotaging the iron ore produced by the mines of Nashkel, while bandits and mercenary groups would raid iron shipments that traveled along the Coast Way road. Meanwhile, infiltrated several Baldurian mercantile interests such Seven Suns and the Merchant's League using doppelganger agents. Growing tension in the region surrounding the iron trade would be blamed on the southern nation of Amn. They sought to compound this foreign hostility by spreading rumors that Amn was taking these actions to prepare for war against Baldur's Gate and their Flaming Fist army. The Iron Throne itself would arise as saviors, providing quality ore from their mine in the Cloak Wood, de-escalating the situation and making a fortune. While Rieltar only sought to bring the west on the precipice of war, Sarevok sought to fully carry out the events that would lead to death on the scale of a god. Sarevok built a loyal following of devotees during this time. They saw him as a sort of divine teacher. With the aid of his most–committed servant Korlasz, he established a hidden sanctum within the ancestral crypts that belonged to her family. At some point Sarevok traveled to an abandoned temple of Bhaal located near where the Coast Way crosses the Winding Water. After he routed the Cyricists within, he learned that the saga of the Bhaalspawn would culminate in the Tethyrian city of Saradush.

 
Sarevok attempted to reclaim the divine seat of the Lord of Murder vacated by his immortal father’s demise, but his plans were thwarted when he was slain by his half-sister, Sora , who rejected her heritage and fought against his Bhaalspawn siblings.
Sarevok’s spirit was sent to the Abyss as punishment. There he eventually crossed paths with Sora a second time when his noble-hearted brother ventured into the lower realms on a dangerous quest to stop another Bhaalspawn named Melissan. Sarevok agreed to help Sora kill Melissan, on the condition that Abdel helped him escape the eternal torments of the Abyss.
Sora agreed, and Sarevok was reborn into the mortal world. After his rebirth, Sarevok was true to his word, and the two brothers fought side-by-side against their half-sister. Ultimately Melissan was defeated, and Sarevok was granted a second chance at life. With his prodigious strength, his legendary skill in battle, and the Sword of Chaos—a life-stealing, enchanted blade—Sarevok became one of the most famous mercenaries in Faerûn. Yet his many accomplishments brought him no joy. He felt no thrill at victory in battle, no delight in the routing of his enemies. The power he accumulated was bitter as ashes on his tongue, and he became a man haunted by his former life. The realization that no earthly achievements could ever compare to what he once almost had—immortality and godhood—left him broken and empty.
Sarevok plunged into a deep despair. To numb his pain, he indulged in every vice imaginable, squandering his wealth and health on alcohol and drugs. While his divine heritage slowed his aging, it did not stop it entirely, and after decades of self-abuse he was eventually reduced to an old man begging in the streets of Baldur’s Gate.
This was how his father—Bhaal, the reborn god of murder—found him. But even though it was dimmed, Bhaal recognized his own divine spark in the pathetic old man, and he sensed Sarevok still had potential. Bhaal recruited him to become the high priest of his fledgling clergy, giving Sarevok new purpose… and another chance to become an agent of death and destruction.
