Good. 

They resurrect one ancestor after another, making tweaks to the distillation process each time. Some of them turn out better than Hiram; some turn out worse. Slowly, agonizingly slowly, they make improvements. 

The vampirism they can reduce quite a bit, but haven't gotten the trick of entirely eliminating. Joseph gives blood without complaint and makes thorough notes. 

The dulling of the senses they can chip away at, bit by bit, until it's reduced to a barely noticeable hint of numbness. 

Then the question, once Hiram recovers, becomes if they with to return Amity, as a fellow researcher to make further improvements, or Eliza. Amity won't mind the current state. Hiram's uncertain if Eliza would.

"I don't...think so. But gaining more information and skill first can only help." 

"And the vampirism should not last long, now."

"Yes." 

They make the preparations to raise Amity. 

She opens her eyes, takes a deep shuddering breath, and begins to weep.

Hiram steps up to embrace her.

Joseph casts his eyes in the direction of the door to where Eliza's body is kept. 

"What has come of the family since my death?"

Emma summarizes, mostly the recent affairs.

"Good. Good. I shall of course exercise all I may towards improvements. There were thoughts I had I dared not carry through upon, nor even commit to writing... And I came across much of assorted interest, in my time as a seminary professor." To Joseph: "I can say I hardly feel the distance from my body that had been so reported, and the blood-thirst is but a distant awareness for now."

"We worked very hard at improving that." 

"My thanks. I have certain insights I believe may help, regardless. If we may retire elsewhere?"

"Certainly." With Hiram's assistance, they actually have clothes that fit her-in-particular, even. 

Good.

One thing she had considered: the incantation seems to call upon a certain being, which some rumors of passed through her hands. She never pursued them in depth, deeming it wiser to not walk that path, but the rumors included that some people have a closer tie, and might be more adept at the incantation.

She also lived a long, academic life, and knows more languages by now than any of them - it is safer to read an instruction manual in the writer's native tongue - and knows of, though she never acquired, several more obscure alchemical texts they could pursue the acquisition of, which would likely aid in their understanding surrounding the distillation process.

"I'll inquire about those at the University library."

"I have some contacts I can pursue - I don't suppose anyone has ideas about finding someone affiliated with beings from the outer spheres? Especially friendly someones?"

"Listening to rumors and other social activities have always been your forte, Mother," he says affectionately. 

She smiles. "I suppose. I'll dig through what we have on the outer spheres and those touched by them, though I suspect 'unutterably strange' will be the extent of most rumors."

"I'll see if I can find out anything about who's been looking into certain books." 

"That would probably be the best use of the two of us; it won't be too strange, if your foreign cousin and his equally foreign newlywed wife wish to spend some significant amount of time secluded."

Nod. "It's going to be harder to explain Eliza." 

Amity makes a politely curious noise.

"Eliza is the woman we're wishing to return most," Emma explains. "She's Joseph's fiance."

"I understand. Could you move, to somewhere no one would know her face? Or if we master this so thoroughly, we might be able to reveal it as - a marvel of modern science, a work of god, whatever the mood of the period has turned to."
