Still recovering and reorganizing stuff but i hope things get better soon.
Also, turns out i still had yet another idea for character related stuff.
There's a rare health condition called Situs inversus where someone's organs are flipped/mirrored and i thought this could suit characters implied to be from "mirror universes" whose anatomies are also flipped but it's normal for their case.
Because an idea i had for the Nortubel 6 was there being "age swap" versions of them, where the older/younger sibling switch ages and come from a different universe.
