#let me stain my souls in ways that are not smen. I wanna piss off the judgements by poking the red science and liberation

This is what I got with my main from the Museum of Souls in Burrow, having your soul examined. Thinking about the soul flaws from skies and I just learned from the wiki the text is variable based on your quirks:

First, for comparison, the text from skies for when your soul is pleasing: "The devils of Carillon claim to be experts in the assessment and improvement of the soul. They would describe yours as tantalisingly opaque, and rich with personality."

Now, onto my interpretations with the delightful flaws. (I refuse to be appetizing!)

High Melancholy: Flickering: "Soul-light is unpersistent, incurious, lacking. [...] intermittently tantalising with an aftertaste of disappointment."

"Here the Devils treat flatterers, the excessively malleable, and those who don't know themselves at all. [...] Maybe you've found yourself lying as a matter of course. Maybe you've forgotten a few inconvenient aspects of yourself."

High Heartless: Cold: "The soul is icy to the touch. Dispassionate, clinical, removed. [...] still, pale and chilly to the palate."

"Indifference to love can be corrected. But not easily."

High Austere: Lightless: Here, things get a little complex. The echo uses "flavourless" which corresponds neatly to "[...] distressingly bland, inoffensive and liable to dissatisfaction." However, Lightless is also described as "Slothful, viceful, willful abandonment of talent and interest," which does not fit Austere. More of the text does, though.

"Vision, imagination, the ability to see beyond the nearest convention: that's what the Devils are trying to evoke here. [...] Perhaps you have fallen into habits. Perhaps you haven't stretched your imagination lately."

Not a perfect match, but alas.

Low subtle: Clear: "Soul is fully transparent. No swirls, no clouding, no personality."

"Disregard of death is a serious flaw. It displeases the Blue Kingdom; it makes the Devils tut."

(Sticking my tongue out at the Sapphir'd King.)

Conclusion: I can't find any obvious comparisons for the ruthless or hedonist quirks. I'm going to remark upon the soul flaws that don't present parallels here.

A fermented soul is "pungent of odour and indifferent to taboo." What I did in skies to get it was commingle with a rubbery man and accept an eye tattoo from the Halved. Good times. If I had to guess, I might connect this one with the Daring quirk. Fermented foods may be described with a "sharp" flavor but that's a stretch; I really don't see a connection to ruthless.

A curdled soul is "Overly willing to please, envious, obsequious." I can't think of any obvious quirks this would correlate to.

Finally, a stained soul: We know what terrible things this means in FL. One gets it by being a seeker, asking what shouldn't be asked. From skies: "Soul appears damaged, scorched. Reckless, dangerous and fatally curious. [...] over-rich, cindered and irrevocably damaged."

"Perhaps you've looked into topics you should not have. Perhaps your soul has been consumed and spat out again by an unspeakable beast."

("The starveling cat! The starveling cat! Soiled your soul! Grew glossy and fat!")

Now go forth and consider your characters' souls. Be unappetizing!
