Laibach of the Abyss was an Old One who coerced Spike into doing its bidding by possessing Drusilla, threatening to completely destroy Drusilla's mind and render her catatonic unless Spike obeyed. Under Laibach's orders, Spike returned to Sunnydale and its Hellmouth, reclaimed the Sunken Church in Laibach's name, summoned the necromancer Matereani, gathered the Dreamers in Sunnydale, and reformed the Order of Aurelius. All of this was so Laibach could resurrect the Master and then bring forth an army of demons on Earth by using The Dreamers to build a bridge between Laibach's world and Earth and using the Master's expertise in opening portals to do it. However, this plan ultimately failed when Xander Harris and Rupert Giles exorcised Laibach's spirit, and the Master was exorcised from Angel's body to be recorporealized and killed in combat by Buffy Summers once again. The Dreamers were also killed by Buffy, preventing any way for Laibach's plan to work.
Though he only spoke the ancient language of Primordial Sanskrit, others appeared to understand him and he seemed to understand English.
- In the game, its not actually made clear how Laibach first made contact with Spike. For the majority of the game, he has possession of Drusilla, but this happens after Spike performs a spell from a book stolen by Malik from Giles.
- Though the primary force behind the events of the video game, Laibach only appears in the cutscenes where he possesses Drusilla and threatens Spike and briefly during the Master's resurrection ceremony where he runs off after the celling begins to collapse. For the majority of the game, his exact role in the events or what he actually is is unknown until Spike defects to Buffy's side after Malik's death and tells her of Laibach and his plan.
- Spike calls Laibach "a Big Badder Old One," referring to Spike's love of calling himself "the Big Bad," a title he uses several times during the game itself.
