Greetings, fellow bricks, I have updated my chapter 5 concept! This post will be long but trust me, it's very much worth the read!
Darkners (And Lightners):
Asgore made the flower king dark-world (duh) and most of these guys are his actual servants. Paige, Weedle, and "Fred" don't directly work with him.
For the main 7 flowers, they are considered "royalty" amoung the others as Asgore's adopted children. Canny and Flax are the only real siblings there, which makes them closer than the rest. (Not to mention that they are both weirdos)
Personality-wise, Canny and Flax are very active and lively, Flax is a bit more devious with it. Marig is also pretty active but far more serious with his "job" to guard Asgore. Basel and Iris are the most chill, Basel just wants to be nice and make food for his kingdom, and Iris kinda just wants to dance and worship her "lord". Lilac can be chill or active depending on the situation, she kinda just wants to read books and sneak around.
Daffo, of course, is built different from their family. Daffo holds a bit of a grudge for Asgore, and wants to replace him. Outside that goal, Daffo is an active wannabe villain who really wants praise.
The guards, Rose and Tullip are pretty much inspired by Zappers. They guard the kingdom and are strong when challenged. Rose is very sweet when off-duty and likes to joke a lot. Tullip is ok with Rose's jokes and is tolerant of most trouble. (As you can see, they get along!)
Possible receptionists are Peony and Spock. Peony can come off as mean, but is really just tired of everything around him. His coworker, Spock, tries to make others understand him. Both are confident but just display it in different ways. They'll probably have an update on their roles within the castle.
Herb, Loam, and Bagger kinda fall in a "helper" category. Much like Basel, their jobs are to restore castle food and drink supply, as well as clean the castle. Bagger often doesn't do his job while the other two actually follow orders. Loam has anger issues and hates his job like Peony. Herb is chill and okay with his long work hours.
Kath, Paige, and Weedle don't have categories unlike most of the guys i just mentioned. Kath is an entertainer of sorts with a low status. (Butt of the joke) Paige is like Hacker from the cyber world but is more shady and has huge ties to the holidays. Weedle is a true outcast. She's seen as a pest to the castle and is pretty much avoided by most. Due to this, she tends to hide and is quite shy.
Fred is built different. Bro doesn't even belong here at all. Similar status to Weedle, except, he's actually just IMAGE_FRIEND trying to look normal in a dark world that clearly isn't his. For now, he's quirky and likes to mess around with the kingdom.
And finally, King Asgore himself. My guess is that he opened this dark world as his "promise" with the black shard since we literally don't know what that's about. He's currently stressed and not in a good mindset rn. This is bad for the kingdom.
If you reached this point here, congrats! You can read! I might make more content about this prediction in the future, as I am hyperfixated on it!
