"I think any grand plan that doesn't involve me going into the Red Wastes once I'm ready would be irresponsible, but it's true that your son's party had no similar excuse. Unless they did? It's strange they'd go to such extremes for merely generic treasure."

"Oh, the rumors of treasure are decidedly not generic. There's said to be a royal armory full of Adamant equipment - and if anything will have survived such a long time exposed to dhar, Adamant would. It's extremely valuable, quite possibly the strongest metal in the world."

"Does someone involved in this have an urgent and specific need for Adamant, then?"

"I wouldn't know if that were the case. It's merely incredibly valuable, for most people. I suppose anything stored in the ruined city might have particular meaning to Dwarves, if I remember my history correctly."

Eefina hums thoughtfully.

"I guess that isn't really relevant to cleansing your son. I'm just a curious person by nature."

"It's perfectly alright. I did say I'd talk to you if you wish."

Eefina nods with a smile. "I just don't want to be nosy. Maybe you could tell me about any fun rumors you've heard?"

"Oh, I'm sure high society gossip would bore a young thing like you half to death!"

"I wouldn't assume you're wrong about that..."

She'll give distracted gossip about the latest parties and who was embarrassed at them, and who commissioned what artist and whether they spent an impressive amount of money on it, and the unconfirmed rumor that Count Draken's daughter (a B-rank adventurer having adventures somewhere off to the west) is dead, and stories of violent social upheaval in the island nation of Gisu which is negatively impacting the tea trade (clearly the most important part of the situation).

Nothing jumps out at her as relevant, but listening to it helps her feel out the shape of the blank spaces in her mind, the context she doesn't have about noble life. It's not actively boring, anyway.

She can also have some speculation that the marriage between this and that house might be off since the daughter's dowry was mostly in tea-related assets and oh here they are at her fancy city manor! It's certainly a fairly conspicuous display of wealth. Inside are rather a lot of precious metals and conspicuously magical things. A maid is waiting for them to arrive and bows demurely to welcome them inside, but has definitely checked Eefina for plausible threat-level.

Gabriella von Runestet is excited, frantic. "Come, come! The doctor's here, he's upstairs-"

Eefina's plausible threat level and her actual threat level are probably dissimilar, though she couldn't guess in which direction.

She hurries upstairs in Gabriella's wake.

There's a room whose walls positively shine with the winds of Hysh and Light, and when the door is opened a repulsive mist of dhar seeps out before being annihilated by the Hysh shining in the open doorframe.

Dhar is... Disgusting, like rot, an ugly corroded blackish-brown entirely unlike the wholesome and wild amber-brown of ghur.

Inside is a thicker cloud of dhar, and a young man chained to a bed, writhing around in pain, with multiple visible mutations - a grossly muscled and clawed right arm while the left is unaffected, an extra mouth on his belly, gnarled and malformed horns, patches of angry red skin- And positively reeking of dhar warring with the normal energies within him. It's a grotesque, disgusting scene, doubly so to Windsight.

Oh, and there's also a tense doctor with his own aura of Light coming from a heavy-duty staff he's brandishing as a ward against the disgusting magic.

"...If you can cleanse dhar, young one, I will attempt to right his body. Perhaps it will only end his misery, and if so, so shall it be."

Eefina flinches, a full-body shiver of revulsion. Windsight is a new sense, but a strong sense, and she feels it very intensely.

The scene itself is much less revolting, but it is certainly motivating.

Eefina hurries into the room, hands aglow with the silver void. She reaches out, and the soothing waves of Curia bloom out toward the tormented man on the bed. And in its path, dhar ceases to exist.

As dhar evaporates, more pours out of the mutated portions of the body, a deep well of it saturated so densely that Curia cannot clean it all so quickly and easily.

The doctor is clearly astonished that this is actually working! He doesn't let that stop him from moving in and performing magic of his own, efficiently attempting the same sorts of healing that have failed on this patient a dozen times before.

The mutations start to recede under prayer and chant and potion and wand and Curia.

This is draining her mana reserve, but slowly. She can keep it up for hours. And she makes sure to except the healing magic from what she's nullifying, so the doctor can work freely.

It might take hours. The dhar just keeps coming back, refreshed by the physical manifestations of its taint in the real world.

It doesn't end up taking hours, plural. Just the one. The doctor seems fairly exhausted, and tuts about triple-checking the unconscious but apparently healthy man lying in the bed.

"Amazing. Cases such as this are rare. Generally fatal in short order... Either directly or by, ah, lynching. But every indication is that he is free of corruption. There seems to be some permanent damage..."

Eefina waits for the doctor to finish, having done her part, and having no particular ability to help with injuries.

He snaps out of it after a bit.

"Thank you. What a fascinating skill. You go tell Mrs. Runestedt the good news, please. I'll be - catching my breath."

"Okay. You're welcome!"

Eefina goes to find the noble lady.

She's just outside the heavily-warded door, pacing nervously. When she sees Eefina, a hopeful look crosses her face.

"It worked."

She lets out a relieved gasp. "Oh! Oh by the Light, thank you! Is he - Safe to see?"

"I think so!"
