The Omega Timeline is a timeline that works as a meeting room for all other timelines. No one knows of its existence or how it gets there unless they are told by CORE!Frisk.
The Omega Timeline (OT) is a special dimension that connects all Undertale timelines and AUs. It has become a new home for people whose timelines are no longer habitable or have nowhere else to go, as well as a safe place for those who don't have one in their own world. That doesn't mean this timeline is only for people experiencing hardships, however - anyone can be invited if CORE!Frisk chooses to do so.
While the dimension has always existed, it was CORE!Frisk who has claimed its ownership and with the help of many shaped it into the safe haven it is now. The first person other than Frisk themselves has set foot in the OT approximately one thousand years ago. The place was at the time empty safe for the entrance, and it was - quite frankly - depressing and sensory depriving. Joining their forces, people started to bring in items and resources from their old timelines, including the stone to build the paths from and the ground to plant the trees in. Through the decades of hard work, the OT has finally become a place worthy of being called haven. The process is still not complete, and the timeline continues to develop more and more.
To someone new to this place The Omega Timeline might look like an average little town; the most notable difference being the lack of horizon, and especially the blank, featureless sky with occasional blue clouds (the recent achievement made possible by the brilliant minds of the OT who grew sick of the white nothingness above their heads). Perhaps the most jarring cultural shock the newcomers experience is the lack of day-night cycle and proper weather, something yet to be achieved through the magic and science. You should sleep with the curtains closed until we figure it out
However, the sky will inevitably always be blank white without any moon or sun, and thus without the day-night cycle. Recently, the local scientists were able to develop special weather satellite machines hovering high above the ground that create blue clouds able to rain or snow, making a gust of wind every time they fly over above. It was a revolutionary invention to mimic weather and make the blankness less potentially maddening.

The timeline was found by "CORE!Frisk", who was thrown into the CORE by Sans after resetting their timeline multiple times to relive the True Pacifist timeline. CORE!Frisk, not knowing that Sans could remember everything from the previous resets, kept resetting over and over again until he threw them into the CORE.
Fms made this promotional art for the OT! He's one of our many cool and talented artists here! And yes, all the people in this are some of our regulars!
- While most believe the OT to be a place for Genocide route survivors, there are many there that are just there to meet other people!
- The OT most know of is a white void, but the capital consists of many different buildings and areas for others to explore!
- There are some occupants of the OT that are called "Caretakers," and they help keep the peace between all the people.
- To all of you asking, no one can be hurt in the OT, except in the White Void. So sadly, no Genocide routes are possible.
- More question answers; Glitch Hop isn't going to destroy the OT.
We've gathered an army in case that ever happens
- Everyone is able to access their own AU from the OT, but they can't access others'.
