Editing Challengers of the Unspeakable (section)

===Oblivion===
After returning to Rathna, Myra explained that after analyzing Vyrellis's notes the portal would need to be closed by creating a "primal anchor," a concentrated magical ward against aberrations utilizing four aspects of magic: life, death, the sun, and the arcane. Given the magnitude of Tephra's actions, the primal anchor would need to be made from divine sources of magic. Vyrellis recommended using Nerull's scythe ''Lifecutter'' as the source of death magic and the base of the spell since it was used to open the portal. Gryff's mace would suffice for the sun magic, leaving only life and arcane magic sources. While they debated what to use for them, they received word of a massive planar disturbance to the south.

When they arrived, they witnessed a massive meteor explode out of the sky and crash into the ground, leaving a planar rift in the sky. After they killed the slaadi who emerged from the meteor, a vast abomination of darkness began emerging from the rift and began extending miles-long tendrils and shadowy maws out, devouring whatever living creatures it could find. Kayleth began a ritual to channel the chaotic energy of Limbo - from whence the meteor had come - back into the rift to seal it before the creature could fully emerge into the Material Plane. As the ritual concluded in an explosion of chaotic magic, the abomination was pulled back into the rift but something to the south was stabilizing it and preventing it from fully closing. As they journeyed, they found the once lush jungle now dead and rotted. Then a glowing figure calling herself the Blessed Angel appeared and told them that they had been gone for three years, during which time Tephra had unleashed the horrors of the Far Realm upon Syra and achieved her ultimate victory. She told them of how Orcus took the Tomb of Horrors as his new throne and churns out endless armies of undead. She told them of how the gods gave up the world as a lost cause and abandoned it, sealing the plane so the madness of the Far Realm could not escape. She told them of how Lolth had been freed, and was now the only god presiding over the ruined world. She told them of how after Theriana slew all the Brightstone Heroes save Leardon, whom she imprisoned while she searched for his phylactery. She told them of how the mind flayers had emerged from the Underdark and scoured Estorium. She told them that it was pointless to fight against the apocalypse; the world was beyond saving, and there was nothing more to do but wait for the final end of creation.

The heroes refused to accept that what she told them was true, however. They traveled to Brightstone Keep to kill Theriana and rescue Leardon, but found him to be mostly insane. The Blessed Angel told them that their efforts were meaningless. They slew the mind flayer Elder Brain in Estorium and found Vyrellis; though she had already been subjected to ceremorphosis to turn her into an illithid, she gave them her journal to read. The Blessed Angel asked if they had a sick fascination with attempting suicide. When they entered the Tomb of Horrors and destroyed Orcus, though, the Blessed Angel finally revealed the truth: they were actually in a layer of the [[Abyss]] known as the [[Barrens]], and she was really the demon lord [[Oublivae]]. Having grown tired of playing with the heroes, she shed her disguise and attacked them.

Though they defeated Oublivae, Kayleth was hurled into a bottomless pit and lost in the Abyss. With the demon queen defeated, the remaining heroes found themselves hurled back into the Material Plane next to the dormant meteorite, where they watched the portal in the sky close close on itself and vanish.
