Not caught up with any lore but I'll sum up most of what I know
Dream build nation, invite friends
invite Tommy and Tubbo. Tommy destroys. Tommy's banned. Tommy's unbanned, finds discs. Dream takes discs, (A)T&T gets the discs backs.
Wilbur joins, makes "dr^g" caravan and then nation. War starts, war won. Nation blows up. Nation rebuilt. DoI signed. "SUCK IT GREEN BOIIIIIIIII"
Nation rebuilt x2, explodes x2. L'Manburg the unfinished symphony. Tubbo executed for being traitor(by techno) and Schlatt dies from a heart attack at one point. Badlands is created.
Manburg v. Pogtopia happens, so does Rutabagville. Rutabagville forgotten, Sapnap and Karl join Manburg. Manburg goes boom.
L'Manburg rebuilds, Eret starts to rule somewhere. Tommy gets exiled, chills with Ghostbur for a while before being ghosted at his exile party. Someone finds an egg in their basement, can't be that bad! It was bad. Tommy wants to die but Dream beats him to it. Butchers created, butchers don't butcher anything. Techno says "Government are die"
L'Manburg parties, supposed to assassinate Dream but Dream blows up Community House.
Lots of switching sides now Techno goes with Dream and Tommy goes with Tubbo. Dream has the best music now.
Hounds kill everyone, withers destroy everything, TNT finishes everything off.
Everyone splits and now Ranboo has amnesia and a voice inside his head
Ghostbur chills in purgatory.
Tubbo likes nukes. Blob is behind bars now but Techno breaks him out after long time. Eggpire tries to take over the world, ignoring King Eret.
Tommy annoys Dream while locked inside prison due to security breach[COME ON SCOTT CAWTHON HOW DARE YOU LEAVE US.] Tommy dies fr fr this time. Lotsa people cry. Statues built.
Syndicate slays(literally) Dream resurrects Tommy because he can then creates chaos by reviving Wilbur. Sam saves Tommy. Schlatt comes back as Glatt[sounds like a f**king spice or sumn]
Chaos chaos chaos, blood blood blood, everyone hates everyone, and so it goes.
