What exactly are the Other Weemas? Alternative universe? Past incarnations? Evil shadow clones? Brand new guys?
They’re a little bit of all of the above? They’re moments in time, captured by Chance, who is an (ACT 3) boss monstah like Vrylls, meaning she’s a Seer , she is a descendant of a species of monster who possess a house and everything it’s ever known, meaning she’s got a catalogue of every person who’s ever lived at her disposal, just ask for a name and she’ll conjure a replica. She doesn’t have their memories, and the replicas are incapable of using magic. Chance, has no idea what she’s doing btw, she can’t control these Weemas. After hearing word and a loose description of a magician named Hahrima, with each dungeon floor being the size of earth, and each dungeon floor being as old as earth, there have been plenty of moments in time that match that description. So she offers you a few Hahrima’s to help.
There’s not a pattern with Hahrima’s, per se, it’s more so dumbed down options gave you a handful of Hahrima’s similar to yours. They don’t represent a pattern with an individual, they’re all just kinda “What If” Weemas with similar actions but totally different philosophies. Act 3 is all about the Game Hen so we do need to understand the magic that makes it in order to understand the Game Hen itself .
The Hahrimas ARE their respective Hahrimas, despite being channeled replicas they have all their memories, and you can assume they act exactly like they would have. Because they are parts of chance they’re not thrown off by the sudden rush into existence they vaguely understand what’s going on and the rules of the house they’re inside of.
