- — Sahjhan and Daniel Holtz[src]
Sahjhan was one of a race of demons known as the Granok, who thrived on chaos and violence. Deciding that the Granoks were too chaotic and unpredictable, Mesektet and Wolfram & Hart used a spell to render them, including Sahjhan, non-corporeal. Though it was meant to prevent the Granoks from doing anything but watching and talking, Sahjhan developed the power to travel through time and dimensions, earning the nickname "Timeshifter."
Eventually, after the birth of Angel's son Connor, Sahjhan travelled back to the 18th century to recruit Daniel Holtz, a vampire hunter whose life was destroyed by Angelus and Darla, and made a bargain with him to take him into the future and have another chance at revenge, claiming to despise Angel himself; in reality, however, Sahjhan intended to have Connor killed because of a prophecy foretold in the Nyazian Scrolls, which claimed that Connor (the one fathered by the vampire with a soul) would grow to adulthood and kill him. As part of his plan, Sahjhan traveled back in time and altered the parts of the prophecy concerning his death to read "the father will kill the son," leading Angel's friend and team-mate, Wesley Wyndam-Pryce, to believe that Angel would kill Connor.
However, Sahjhan grew impatient with Holtz when, instead of simply killing Connor, he laid out an elaborate scheme to kidnap Connor to get revenge on Angel once and for all. Faced with this, Sahjhan turned to Lilah Morgan for help, who spiked Angel's supply of pig's blood with samples of Connor's blood she stole from the hospital, causing Angel to become increasingly violent. Out of fear for the baby's safety, Wesley made a deal with Holtz and kidnapped Connor, only to have his throat slit by Holtz's right-hand man, Justine Cooper.
In the midst of a four-way confrontation between Sahjhan, Wolfram & Hart, Holtz's forces, and Angel, Sahjhan opened a portal to the hell dimension Quor'toth, threatening to suck everyone into it. However, Holtz took advantage of this to jump into the portal himself, taking Connor with him. Deciding that Connor was as good as dead in Quor'toth, Sahjhan closed the portal behind them.
Enraged and grief-stricken, Angel used a spell to recorporealize Sahjhan, intending to kill him out of revenge for Connor's disappearance. In the ensuing confrontation, Sahjhan revealed his plans and that the prophecy that led to the kidnapping was faked by him before taking on Angel. Sahjhan quickly proved too powerful for Angel to handle, and he was just about to stake Angel when Justine arrived and used a Resikhian Urn to imprison Sahjhan out of revenge for Holtz's disappearance.
Two years later, Sahjhan was released under the watch of his old enemy Cyvus Vail, who wanted to fulfill the prophecy and have the now-adult Connor kill him. Though he was initially overwhelmed, Connor eventually prevailed and decapitated Sahjhan, thus fulfilling the prophecy after all of Sahjhan's attempts to prevent it.

Along with his species' trademark viciousness, Sahjhan possessed a sarcastic and dry sense of humor, often cracking jokes and puns; he even claimed to have invented daylight savings time.
Powers and Abilities
In his solid form, Sahjhan possessed incredible strength and durability, able to effortlessly flip a two-ton pickup trick "like a Tonka toy" and outmatch Angel in a one-on-one fight. He also possessed extensive knowledge of dark magic, able to open dimensional portals and rip holes in the fabric of reality, the latter of which seen when he opened a doorway to Quor'toth; however, he claimed that if he attempted to open a doorway to Quor'toth again, it would destroy the universe.
While incorporeal, Sahjhan was still able to manipulate physical objects, as well as freely travel through time and dimensions. He also had some control over the electromagnetic spectrum, able to turn off television sets with a wave of his hand.
