How to Unlock Edith in Sovereign Tower

Edith is stammering over a garden pond, unnerved that nothing magical is happening in it, the opposite of Moonvale’s spell-charged lakes.

Dialogue Choices:

“Is the ecosystem there that different?” (no affinity change)
“That’s disappointing. I’ll make sure to curse the pond.” (no affinity change. She recoils: “But your lands are far too devoid of magical energy to hold even a single spell…”)

Either way she explains that recreating that effect would need an arcanist permanently chained to the task, “like a slave condemned to breathe over the water’s surface,” then asks how you’d rather see her talents used.

Dialogue Choices:

“How do you prefer to spend your talents?” (a genuinely open question back to her) (+Affinity. “I’m glad when my knightly talent precedes over my esoteric gifts…”)
“You’re a good mage. Your skills will indeed be useful elsewhere.” (no affinity change. “Y-yes… but I mainly want to be a good knight, Your Grace…”)
“You’ll do what I ask you to do.” (Tyrannic) (+Affinity, and raises the Tyrannic sovereign tag. “Y-yes… obviously. But…”)

This one is worth flagging since it doesn’t sort the way you’d expect: the curious option and the commanding option both raise affinity, the reassuring middle option does nothing. She circles back to her sword’s name, Dansleif, and you get to ask about it either directly or through what it means to her.

Dialogue Choices:

“Why not focus on your magical skills?” (asking about the sword directly) (no affinity change. She says she comes from a lineage of powerful Moonvale mages, and admits she froze under the weight of the breastplate when she first trained, “but I fought”)
“Where did you find this sword?” (no affinity change. Dansleif is a legendary blade of Moonvale that she found sealed and freed herself. “It’s a legendary sword of Moonvale… and it belongs to me. TO ME.” She tightens her grip on the hilt while she says it)

The scene closes on Edith pressing her ear to the blade, murmuring, before catching herself: “Anyway, I’m infinitely happy that you made me a knight at your Table, Your Grace. But… you haven’t forgotten that I’m not made to MURDER others right…? Thank your, Your Grace.” Worth remembering for later.

You find Edith in the library’s Occult and Demonology section, twirling dust off a shelf. She offers three lines of questioning.

Dialogue Choices:

“Which book would you recommend to a novice such as myself?” (+Affinity. “The Traps of Arcana,” a work of “questionable reliability”)
“Which book has taught you the most?” (no affinity change. “Rites of Angelor”)
“And what do you know about demons?” (no affinity change. She goes still, “purely as an object of study, of course,” and it was the subject of her final-year thesis)

The book-recommendation option is the only one of the three that moves affinity here.

You find Edith sitting motionless in the kitchen in front of an untouched dish, speaking in a flat, mechanical register: “Your kitchens are overflowing with succulent fare… Yet you haven’t eaten anything.”

Dialogue Choices:

“…Yet you haven’t eaten anything.” (pointed, suspicious) (no affinity change. “Indeed. I’d rather wait a bit. My dish is still hot.”)
“Thanks.” (accepting the small talk at face value) (+Affinity. “You’re welcome.”)

She keeps talking in that same cold, mechanical register, “I feel good today… I hope you’ll send me on another mission,” until you can push on how she’s acting.

Dialogue Choices:

“You don’t look… so good.” (leads into the same follow-up either way)
“…Are you sure everything’s alright?” (leads into the same follow-up either way)

She asks, coldly: “Did you prefer me when I was trembling and hesitant?”

Dialogue Choices:

“Yes.” (no affinity change. “That seems terribly cruel on your part.”)
“Answer the question.” (deflecting) (no affinity change, skips straight past the accusation)

Dialogue Choices:

“Sealed your fate?” (routes to the reveal)
“*Us*?” (gets you the chilling correction: not “me,” but “Two passengers.”)
“Can you not be clearer?” (routes to the reveal)
“(Threaten) Reveal the whole truth, or be banished.” (routes to the reveal)

Push far enough and the demon explains itself plainly: “You simply awakened the demonic power that dwelled in the sword of that unfortunate Edith. Me. From then on, all that remained was to harvest her still-warm body.” Ask how to reverse it and you’re told flatly there’s nothing to be done. The scene then offers an actual banishment prompt, “Leave. You are banished from this tower,” with two real outcomes.

Dialogue Choices:

Accept the demon (Edith, or what’s speaking as her, thanks you, and it unlocks a special dialogue flag tied to another demon presence elsewhere in the Tower)
Banish the demon (“You cause pain to Edith, Grace. But so be it,” and it triggers her dismissal from your Round Table outright)
