A while ago i made a post about a pretty unserious twomp hc (this post) that i have that ties to my headcanon that twomp takes place at some point of the 2000's maybe early 2010's at latest but i never elaborated on the later. Today i was feeling like talking about it.
I began to think about this when i realized that the technology shown in the episodes isn't the most modern, we've seen landlines and this type of tvs ⬇️ (idk what they're called in english)
And that's it. For comunication most void residents seem to use only two methods: phone calls or letters.
But then i thought; what i consider to be modern technology is human made technology that'd have to be introduced to the void by the humans who've recently started moving in, maybe it just hasn't happened yet. There's also the fact that making technological connections work between different voids might be complicated, this could be related to letters being a fairly used way of comunication.
As i was overthinking technology in the void i realized that there's a much simpler way to back up my hypothesis about the time setting:
Mark!
We know he was 10 y/o durning the events of maf and that maf takes place in 1997 (i have a reliable source for this information, Ashur himself!) Ashur also said that the Mark in twomp is an older, healed Mark. We don't know his age but since he has a job we know he's an adult. (Funny how i have an habit of calling Mark my child even though he isn't that many years younger than my parents)
So yeah, that's why i belive twomp is set in the 2000-2010's.
Uuuuh i think this ended up being closer to a theory than a headcanon.
