The aliens killed everyone on Earth...almost.  Every structure, from the Taj Mahal to the lowliest lobster trap, vanished into the earth, killing everyone inside.  The survivors were given a choice:  Endure on the surface without food or shelter or tools, or descend into a world-spanning nightmare dungeon that is also a reality TV show.  Katia, an art professor from Iceland who has given up her humanity to transform into a shapeshifting doppelganger, meets up with Carl and his cat, Donut.   Together, the three fight to survive in a dungeon filled with Clarketech goblin murderdozers and pyramid-scheme fairy moonshine-makers. The above is, of course, describing Dungeon Crawler Carl.   With DoctorHepa's (the author) permission I'm posting some fanfic to expand on Katia, one of the secondary characters who started off not getting as much exploration as I would have preferred.  I started off writing chapters that matched up to canon except from her POV instead of Carl's; that lasted a couple of chapters before going off the rails and spinning off into a completely new story, which suggests I should really go back and renumber all the chapters as soon as I find some tuits.
