Timeline

Overview
The timeline will have 3 segments:

Pre-Betrayal - Before the point at which Providence trapped Mithrix on the moon.

Post-Betrayal - After the point at which Providence trapped Mithrix on the moon.

Present - During which Risk of Rain 1 and Risk of Rain 2 take place.

Pre-Betrayal

 * Mithrix and Providence (the brothers) somehow exist on Petrichor V, be it born or not.
 * The brothers chase glass frogs in the sun.
 * Providence catches Mithrix tossing worms into a gravity well. -A few millennia pass from this point to the next-
 * The brothers create teleporters, which they call gates.
 * Mithrix learns that he loves design whilst Providence learns his ability to create and shape.
 * Mithrix builds the Bulwark's Ambry for Providence to create anything he wants with the 4 elements of the universe Mithrix found, and in which Providence makes the Artifacts.
 * The brothers, as they reshape the planet to how they like it, talk about Sundered Grove. Mithrix loves triangles, while Providence loves circles/rings. They both love trees, though.
 * The brothers start to create golems, which they call Guardians.
 * Aurelionite is created, and Mithrix has to lock him away as he is sentient and dangerous to him and Providence. This is thanks to Providence adding too much soul than the design needed to Aurelionite, making them powerful and unstable.
 * Mithrix shows Providence how to create a golem with no soul, being the original design of the Lunar Chimera (Golem), which Providence then later used in making the Temple Guard.


 * Many times before "She" came. It is unknown who "She" is, but its known that she is no female that is known in Risk of Rain.
 * The brothers know that "She" is coming again soon, and Mithrix wants to give her some of the gates they've made.


 * Mithrix created the first, and only of its kind, teleporter that can travel between planets, which is known to be the Primordial Teleporter. He does this because he wants to find more of their own species and leave behind the planet, which has doomed species on it.


 * Providence, who cares for the beings on the planet, lets Mithrix go on ahead to the moon. Once Mithrix is there, he locks the way back, trapping Mithrix on the moon. We refer to this point as the Point of Betrayal.

Post-Betrayal

 * Monsters start to get taken by Providence from other planets to Petrichor V.
 * The Elder Lemurians, as a thanks to Providence whom they call their Hero, create the Temple of the Elders.


 * The Imps invade, trying to take over the planet, but get trapped on Petrichor V thanks to Providences physical presence.
 * Grovetenders, as thanks to Providence for helping his ancestors, creates Scorched Acres with his wisps.
 * She had came and died, giving her blessing to Providence. What the blessing was is unknown, but her sacrifice is unknown to the inhabitants of the planet.


 * Mithrix starts creating lunars with help from others on the moon, the lunars being scattered across Petrichor V for beings to grab and become influenced by him, becoming Mithrix's servants.
 * Mithrix tells his servants (primarily being the Twisted Scavengers) to go to the monolith in A Moment, Fractured, and to use it while holding his beads. It sends them to A Moment, Whole, a place outside of his reign of terror and a place that they can have eternal peace.
 * Providence, to try and stop his brother, hunts down those holding these items. Any and all lunars found get put into cleansing pools, turned into Pearls.


 * Mithrix designs and builds the Lunar Chimera (Wisp) (inspired by the Greater Wisps and Clay Templars) and the Lunar Chimera (Exploder).
 * Mithrix details his plans for getting back on his brother who betrayed him, noticing Earth and planning on destroying it by building a Grander Teleporter to get there, all to see the look on Providence's face.

Present

 * Artificer somehow gets trapped by Newt in the Bazaar Between Time. It is unknown when she did.
 * UES : Contact Light goes off course to Petrichor V, to pick up "a matching pair". The detour was requested by an unknown individual, redacted from the blackbox data.
 * After having been around Petrichor V for 2 hours, they put their collected teleporter into the cargo bay. It is unknown how they got them aboard.
 * Providence then appears onboard via the teleporter onboard, smashing the ship as it starts to crash in a span of 5 hours. In said 5 hours, the Heretic Kur-skan appears on the ship via a blue portal, rushing to the front to repair the ship so it can fly, so she would be able to escape. She failed doing so, as Providence appeared behind her and killed her.
 * The ship spilled all of its contents across the entire planet and space around the planet, with survivors escaping via pods and ships to the planet below.
 * Most of the escape ships crashed, but the ones that survived made Rallypoints, like Rallypoint Delta, for reconnaissance.
 * Out of the escape pods that shot out of the ship, one contained Commando, aka The Survivor. The Survivor, in the span of a few weeks, traveled through the teleporters to reach UES:CL. They are the ones who killed Providence. They documented their time on the planet via the monster logs and some item logs, the items being classified as field-found.  The Survivor is also the only survivor to escape the planet.
 * The rest of the survivors across the planet died out, some fairing for a while like with Rallypoint Delta, but all-in-all dying in the end. Acrid is the only survivor in both games who are the same being, thanks to them having been captured by the Void Reavers.  - Skip a few years -
 * UES [Redacted] appears for the distress call of UES:CL, the ship having multiple units for exploration, sciences, hydroponics, etc.
 * UES [R] go across the planet to explore, documenting monsters, environments, some shipping crates of UES:CL, and other things.
 * Some scientists on UES [R] find the Artifact Teleporter on Sky Meadows, creating the technology around the teleporter having figured out the things behind it.
 * Other scientists dissect monster parts, while exploration groups bring in artifacts and materials of the planet that can be studied.
 * During their time around the planet, REX breaks protocol and becomes sentient. The head of the Hydroponics division tells the crew to kick him off the ship, so they do so, which leaves REX in Abyssal Depths.  They are currently unpowered and severely broken.
 * It is entirely unknown whether UES [R] went back to where they came, or died on the planet. - Skip a few years -
 * UESC re-hires a famous retired Captain, who worked on many secret projects for them before, for one last mission. He agrees, asking for the ship he was assigned (being UES : Safe Travels) to be filled with armaments and supplies.
 * Captain then goes out to find and hire people going along with them on the expedition.
 * During the hiring of people, Bandit sneaks onboard UES:ST, as nobody knows each other.
 * They make it to Petrichor V, getting the distress signal UES:CL sent out during its crash. It talks about the monsters attacking the ship. Captain decides to send them down anyway.
 * As the characters make their way through the teleporters, they see escape ships that are broken and crashed. They then reach the moon, killing Mithrix, and escaping.
 * The Void Reavers, just after Mithrixs death, invade the moon and start to try and capture it. They fully send it to the Void Fields after the survivors leave the moon.
