Scheele, Sarqi, Lanuit, Foros?
she is actually part of a "set" to say haha; her, Oropimente and Realgar's names are based on pigments/colors known for their toxicity. In Scheele's case: "Scheele's green" or "Paris green" (although thats more chemical resemblance to Scheele's, this one tho is the one that fits her the most, color/aesthetic?, wise but I liked the name Scheele better tbh).
I'm gonna be honest I forgot why I named him like that, I know it's a bastardization of another word (sorta something related to luck or curses idk), but yeah lol
The night~, the Starry Night one could say 😎
From what I recall, the adverb Foras, meaning stranger/outsider/foreigner
Fun fact: he didnt really care for a name, but he was nicknamed Forrastrero by Ainakea who kept running him out of the graves looking for his "weird threads" as the tundra called them, eventually once they made each other friends Foros just took the nickname and modified to fit him better
