Oblivion
Oblivion is an Alexandrian resistance movement formed by Robor and Alayla to oppose Preservation, and they later worked to stop the fusion of Alexandria and Yyasulani. Sometime later, the group was refocused on opposing Zoraal Ja.
History
Oblivion was founded by Milallas Robor and Alayla after they defected from Preservation when they learned what the collective attempted to achieve by interdimensional fusion: to steal aether from the Source and other reflections in order to maintain and create more Endless, simulacrums of the deceased Alexandrians created from their memories. Robor and Alayla erased all knowledge about themselves, since Preservation was on their trail, as they had spirited away the key to interdimensional travel to the Source. Even the members of Oblivion didn't know their names.
Without its founders, Oblivion effectively ceased to exist until the First Promise of Tuliyollal, Zoraal Ja, stole the key and used it to enter the Ninth, becoming King of Resolve of Alexandria, he and the Queen of Reason, Endless Sphene, now had the means of initiating interdimensional fusion. They fused Everkeep and the nearby region with Yyasulani in Xak Tural. At some point after the event, Cahciua, who was among those trapped in the dome and died during the three decades of isolation and subsequently converted into an Endless, encountered a pair of drunken patrons who just finished a brawl with the Outrunner she uses to interact with Alexandria's living populace. Together she, along with the patrons Geode and Shale, discovered Oblivion's original headquarters in Solution Nine, the Backroom, and founded a new incarnation of the organization based on old documents found within. This Oblivion continued opposing Preservation like its predecessor, while also having a new goal of opposing Zoraal Ja. They mainly consisted of members who opposed the usage of soul regulators, instead favoring the natural way of life and not forgetting those who had passed away.
They could do nothing to prevent Zoraal Ja from invading his homeland, Tuliyollal. They eventually joined forces with the Vow of Resolve of Tuliyollal, Wuk Lamat, as well as the Warrior of Light and their companions from the Scions of the Seventh Dawn against Zoraal Ja. In the following crises, including attacks on the citizenry by Alexandria's automaton army, Oblivion organised armed resistance and protected the people.
Lore
A resistance organization first established during the time of old Alexandria. Its founders were Krile's parents, Robor and Alayla, former members of Preservation who opposed Calyx's plan to invade other worlds. Once the then-infant Krile was targeted for experimentation, the researcher couple seized the key to interdimensional fusion and used it to deliver both the artifact and their child to the Source to keep them safe from the enemy. They vanished from record thereafter, with their Endless incarnations later encountered in Living Memory.
Deprived of their founders, Oblivion effectively ceased to be — until decades later when its secret headquarters, now known as the Backroom, was discovered by Cahciua and her followers. Although detailed information pertaining to the key had been erased, Cahciua, strongly believing in Oblivion's purpose, reestablished the organization under its original name. With the Yyasulani native at the helm, its members set out to thwart King of Resolve Zoraal Ja's ambitions for conquest.
