"Did I stutter?"
There was an edge of irritation in Otis's tone as Chunji decided to completely ignore what he had said. What was so difficult about keeping Davil stable? Did essence exhaustion affect the bespectacled idiot's ears as well as his eyes? But what was done was done. Even though the Strigidae had prepared to begin running tests to test his hypothesis, he had to admit that Chunji's Ethos was faster. It was some form of poison after all, one that was traveling from the stomach to the heart at a rate that was nevertheless much slower than the flow of blood. It wasn't spreading or diffusing in the way that Otis himself would have expected; the manner in which it traveled was unnatural.
In which case, even the stagnation of blood-intake and essence-recovery were just side-effects meant to distract from the real issue: the stagnation of the heart lead to reduced heart rate, which would ultimately cause a cardiac arrest. Fatal, certainly. Or, if it could corrode metal, perhaps it would melt through the heart upon arrival, after having suppressed its 'corrosion' essence up to that point?
Hmph.
That was the problem with cultists. They spent too much time on theatrics without considering practicality. Otis himself could probably concoct a faster-acting poison that was just as lethal. As for coming up with an antidote for one though...
"I don't have a procedure. I'm not a doctor." His tone was flat. "Go find Doctor Kann and let him know what we found. I'll look into the foreign substance further."
It was no longer a needle in a haystack. Now that Otis was aware of exactly what and generally where the unnatural substance was, he could do a refined search. Murmured incantations clarified the nature of the world around him as he dove into the sea of essence that comprised a human being. The world was made of essence, and everything contained essence, but if that substance was only partially melded into Davil's blood, then it should still have a distinct outline. Two human beings hugging each other did not become a singular entity when viewed through a mage's eyes. A spear became a stick and a steel piece, if one changed their perspective.
They needed to learn more.
And Otis loved learning.
...
That being said, he did have at least one procedure in mind.
They could exsanguinate Davil until that poison was drawn out. Worldly problems were answered with worldly solutions, after all.
