Okay, so, I have a pair of fantrolls, and I'm doing my best to not make them Mary Sue. One has a shade or two lighter (not a mutant) than Equius, hates archery, but uses darts. She has a blacksmith shop, and a blood sucking humming bird lusus. The other one is a lavender blooded seadweller mutant. She was Feferi's slave (by order of HIC), and she can see glimpses of the future. She has a snake lusus.

2 things. HIC has never met Fef or have any interest in her what-so-ever so I doubt she’d order her to have a slave. And is slave troll’s snake lusus a water-dwelling snake? Cause her lusus needs to be aquatic.
