Does anyone know what you’d call the trope in fanfiction where
The MC/Ensemble gets isekai’d/sent back in time/banished or leaves
they decide to build their own Homebase/settlement/Nation where they do things their way which is usually better/more advanced than what their enemies/other people do? sometimes they use a pre-existing
Usually with magic/similar powers or with future knowledge/scientific advances.
MC is usually the leader and is leading the charge with the changes. MC draws people in with charisma, power, and revolutionary changes. Side characters are usually the first ones to join the MC
Bad Guys can’t compete(or at least can’t keep up with their advancement), but usually outnumber MC’s group so it's not immediately one-sided in favor of the protags
Sometimes there is a godlike being that initiates the initial send-off to ‘fix’ something although they usually allow the MC to operate how they want to. Sometimes they only care for their own entertainment or are not godly and are out of their depth.
If there isn’t a name for it I propose Basebuilding on the smaller scale and Nationbuilding on the larger scale
anyways, any fic recs? cause I usually read this trope with like Game of Thrones, Harry Potter, or Naruto but I have found it in ATLA and MHA before too. I think I've seen it in the MCU fandom with like Tony accidentally taking over the world, and in the HTTYD fandom with like Hiccup single-handedly creating a Viking renaissance, but I think it would be a neat concept for a Percy Jackson fic.
