Timeline!

  • Undertale and Underfell happened first, UF and US ending up in UT due to fucking round and finding out with the machine in Sans' (Papyrus') lab around the same time. They began doing monthly meetings and get togethers, UF originally planning this as a tactic thing but began to enjoy the non murderous stress

  • Saejun was next, learning that there was a farmtale, Blue wanted to get better ingredients since finding stuff for tacos were a bit scarce so went there a few times.

  • Error occurred next, kidnapping Blue but no Blueberror as the voices convinced Error to let him go.

  • Outer was next thanks to Error, it was an accidental meet but yeah

  • He also met Ink and Fresh around this point but just briefly as they appeared just as he was leaving. The timeline was 'reset' in a way where everyone was back but everyone remembered what Error had done.

  • Blue met Dream next through Ink. Ink, Error, and Fresh being pen pals after the whole thing (started off with Error but the other two joined in) and they created the proper Star Sans' we know today.

  • Blue's crush on Dream begins

  • Blue met the MTT + NM while fighting but didn't actually know them know them just of them

  • Chara falls down and stays with the skelebros for along while

  • Blue officially met Killer first after hearing that Dream wanted to help him, and wanting to prove himself he decided to try and do it himself thus the whole fight.

  • Surface arc

  • Error moves into their house

  • Dust, Killer, and NM he officially met during kidnapping saga

  • CPAU is where he met literally every other AU officially rather than passing since it was mainly his brother who was nosey about that shit or he had to go somewhere with Dream and Ink
