Timeline

The current timeline of the setting and some of its major events.
Outsider Multiverse Timeline
FE=First End (Also denotes Weave Time or Weave Cycles, the shared subjective time between Weave Nodes, as the time travel capabilities of acausal beings render any sort of objective measure of time moot). 
200 000 BFE: First minor time-space anomalies detected. Few civilisations within the Milky Way payed attention to this discovery. Point 0, the universe that the original Weave Outer Gods come from, is on its way to its demise. The Void is discovered from these anomalies. All possible timelines collapsed into the single timeline where the Void was discovered.
199 991 BFE: First examples of Void tech created from this new discovery. 
199 892 BFE: Time-space anomalies grow larger. Swathes of cosmic strings form around these anomalies. Universal Commonwealth founded as Voidtech civilisations expand to the rest of the cosmos.
199 345 BFE: Birth of the first ‘Blank Readers', beings with connections to the dead timelines and an ability to sense changes in the Void's presence within the universe. 
199 105 BFE: Some in the Universal Commonwealth finish the first stage of Transcension, including many Bland Readers. Zero, or Null space is created, allowing for trivial FTL travel to other galaxies and to other parts of the universe and limited warping of universal laws of physics.
146 225 BFE: Universal Commonwealth is formed by the civilisations of the cosmos.
99 435 BFE: Large numbers of Transcends begin the second step of Transcension.
99 434 BFE: The first Void storms form from the large concentrations of Void energy present in the universe. Universe is cut in half by an immense Void storm, barring the superclusters of Laniakea, Pisces-Perseus and Centaurus. Universal Commonwealth collapses. Many first stage Transcends trapped in these Void storms. Void storms irreparably damage large swathes of reality, causing areas of space-time that do not follow the rest of the universe's physics and spawning hazardous and strange phenomena and anomalies.
49 342 BFE: The first second stage Transcends form both within and outside the Void storms. Some remnant polities of the Commonwealth form. Some Void storms clear. 
34 835 BFE: Gradual clearing of some Void storms allow true successor states of the Commonwealth to form. The first iteration of the Aedentide Covenant is formed by the Solar Imperium, Red Star Alliance and the Aeon Network, controlling most of the Laniakea supercluster and its surrouding super clusters. On its opposition is the nation known as Event Horizon, controlling the Bootes Void and many separate superclusters scattered around the universe.
260 BFE: First ships capable of piercing the hostile Void storms built by the Aedentide. Many hope that these can carry them to less hostile universes.
1 BFE: The Aedentide evacuates the universe, carrying the vast majority of Blank Readers and all Transcends with it.
0 FE: First End. Several octillion die as the universe fades away on itself. Without the Readers and Transcends, those still in the dying universe are lost and the final efforts to save the universe are too little, too late. Surviving population only amounts to a few hundred septillion, mostly digital uploads and Transcends. Readers leave behind a small mass, intended as a seed to birth a new universe in the place of the old.
12 FE: The remaining Readers and their aliies find a new universe with relatively compatible laws of physics. Some laws are harmful, and active terraforming is performed on parts of the local reality to ensure the survival of non-Transcend elements. These regions are known as domains
13 FE: First Contact with the native species of the universe that would later be known as Weave Point 01 occurs. The contact is disastrous, as the terraforming effects of the domains formed by Point 0’s civilisations are misunderstood as an attack by Point 01’s natives. The remnant civilisations of Point 0 are either forced into strongholds or destroyed and left to a cycle of destruction and rematerialisation in the numerous ‘Tomb Clouds’, debris of destroyed planets, starships and space habitats. This cycle of destruction and reformation stunts the ongoing Transcension of Point 0’s remnants in the Tomb Clouds.
168 FE: The conflict between Point 0’s remnants and Point 01’s natives reaches a lull and an informal ceasefire is reached. Nomads lead by Arzin makes contact with several Tomb Clouds.
182 FE: Ceasefire ends. Arzin allies with several Tomb Cloud collectives and nearly manage to flee to the strongholds on the edge of Point 01. Arzin is forced to betray the Point 0 remnants after his people are held hostage in a pocket dimension. The Point 0 Tomb Cloud denizens are now fragmented and imprisoned in various pocket dimensions known as Labyrinths.
236 FE: Enough Tomb Cloud denizens have have reached the threshold to complete their Transcension. They are still imprisoned, however, and start infiltrating and undermining Point 01’s civilisations from within through avatars and proxies. Almost all of the Point 0 remnants in the strongholds have also transcended at this point. Several new sapient species appear at this point in time, born from the separated fragments of discarded Transcend bodies.
245 FE: The first full Transcended emerge in both the strongholds and Labyrinths. Under the strain of keeping the Point 0 remnants sealed or repelled, the civilisations of Point 01 begin to weaken.
249 FE: The preparations are complete. Using their proxies and avatars, the Transcended of the Labyrinth break free. The waiting fleets of the strongholds assault the civilisations of 01 in the chaos. The Ascension Wars start.
301 FE: Under the attacks of the free Transcended, the civilisations of 01 are put under unbearable strain. It becomes apparent that Point 01 will fall. Arzin is hunted down and killed for his betrayal years earlier.
304 FE: The Ascension wars end. The last native civilisation of 01 ha fallen. Mass exodus of the fallen civilisations. Some of the Point 01 natives choose to stay, however. The Age of Rebuilding begins. Several groups originating from Point 0 break off, including what would become the Necroan Flesh Cult, Amalgamation of Intelligence, and Mons Olympus.
305 FE to 602 FE: There is relatively little activity during this period during reconstruction. Several minor wars are waged between petty parties in the background. Many Transcended make rapid progress towards their next ascension. The Weave is founded.
602 FE: The first multiversal Transcended appear. These Transcended can now be formally called Outer Gods. Deciding that one universe is not enough for the rapidly growing civilisations in Point 01, new universes are created and other universes are scouted out in the Void. Point 0 is now fully rebuilt and colonisation begins.
603 FE to 3821 FE: Period of relative peace. Near the end of this period, however, tensions appear between several Outer Gods and Transcended organisations as the Weave begins dividing by ideological lines; Archivists, whom advocate extensive intervention in the affairs of powers outside the Weave, Isolationists, which advocate the opposite and a focus on the Weave's own affairs, with the neutral Ascendancy between them. The prelude of the First Aeon War begins.
3822 FE: The First (and shortest) Aeon war begins as tensions erupt. Factions of Outer Gods and Transcended wage an eternal war across time and space within a multitude of universes. The first technologies for protecting Bound from temporal attacks are implemented. The Archivists are defeated by the Isolationists, leading to a slowing of Weave expansion and a period of peace. Universes destroyed during this war were rebuilt.
3823 FE to 350 058 FE: A period of relatively slow Weave expansion and peace, The decrease in action by the powers of the Weave outside its borders have allowed some breakaway groups from the Ascension Wars to gain power and territory. By the end of this period, another Aeon War becomes ready to break out.
350 059 to 353 689 FE: The renegade group of Mons Olympus, backed by foreign Transcended civilisations, assault the Weave and occupy large sections of the network. Mons Olympus has now grown into a bizarre mix of different organisations, all with some past grudge with the Weave's factions. External influence on the group is suspected but never confirmed. Another devastating Aeon War across time-space is waged and, in the aftermath, the minds of the responsible Outer Gods and Transcended leaders are wiped and rewritten through the Opal Light to stop further aggression. The organisation is disbanded.
354 922 FE: The Evolution Olympics are created as a way to bring the various people of the Weave together.
520 459: The Weave begins expanding more quickly, reaching a relatively obscure Outer God by the name of Ilak. This deity is ancient, even by Outer God standards. The other Outer Gods within the Weave attempt to contact this silent ancient, but their replies remain unanswered.
520 460: Ilak is still silent, but contact has been established with cultists and researchers of the mysterious ancient throughout the universe across time. It becomes known that Ilak is in a half-dreaming state, being barely lucid and only just awakening. Ilak is only subconsciously aware of the other Outer Gods and Transcendents contacting him. His cultists seek to awaken him, saying:
“The Great Somnoire dreams and thinks of all that exists in our universe. We seek to awaken him, or at least draw his full attention. Throughout our dealings with his servants and angels, we discovered that they were simply his runaway thoughts given flesh. If his awareness gives us existence, then it is certain that his attention would grant us divinity. Surely, you, as his kin across the stars, would know this.”
520 472: Disaster strikes as Ilak fully awakens. Devastating collateral damage occurs as the universe and adjacent universes begin to destabilise due to Ilak’s more active thoughts. What is unusual however, is that the cultists became Transcended themselves. The Weave is kept away from this Outer God, not out of malice but out of necessity for the dangers that his runaway thoughts could inflict on those of material reality. Contact with Ilak reveals disturbingly little about this enigma.
520 496: The Weave expands around Ilak and his realm to avoid his stray thoughts. New doctrines are created to avoid the awakening of possibly hostile or dangerous Outer Gods.
520 496 to 32 364 243: Records of this period are damaged and hard to verify, with only a few surviving powers being able to corroborate them. The damage done to much of the Weave by Tor was severe, but it is known among the survivors that this period was a Golden Age.
32 364 244-32 364 245: The Tor Crisis. Countless die as universes are corrupted and destroyed while those bound by reality are mercilessly consumed. The Overmind is created in response and formed by the Transcended and Outer Gods by temporarily connecting their power. Adremer Tor is mostly destroyed, but the damage done may never be repaired. The Outer Gods are trapped by Tor's main mass in the region now known as the Creeping Cage. Civilisations on the Weave's periphery are now on their own. 
32 364 245: The Scattering commences. There is chaos as roving bands and petty empires carve out pieces of the devastated Weave. Monstrosities once contained or diminished surge to prey on the survivors.
32 381 232: Establishment of the Weave Remnant in the midst of the Scattering. Survivors are brought together over several millennia.
32 414 939: The Scattering ends. The Weave Remnant sign the Treaty of Eloth with the Warring Throne, in exchange for the latter's protection against the Undari and Selemon, two factions that were peer to the original Weave and and now completely outmatch the Weave Remnant.
32 564 391/Present: The Amalgamation of Intelligence and the Necroan Flesh Cult resurface as major powers. Before the Tor Crisis these two parties were relatively minor groups near the edge and beyond the Weave. They survived mostly intact through the crisis and are now active in taking portions of the former Weave for themselves. All the Tor crisis survivors within the Creeping Cage are rehabilitated by the Transcended and Outer Gods in the relatively small portion of intact Weave left within after the Tor Crisis. The stage is set for a third Aeon War…
