(freewriting - Selcouth experiments on some Lethean tea leaves.)
You watch as the Meticulous Apothecary performs test after test. They immerse individual leaves in glowing reagents; powder them beneath amber tools; examine them as they burn through an array of lenses.
After every single experiment, they take notes. They write pages of observations. They decant their slime into sealed vials. They rhythmically squeeze lumps of amber in their tentacles. They carefully wrap every individual item before boxing it up, and then for good measure, they label the boxes themselves.
(You are beginning to understand how they remember so much, despite the nature of their work.)
Finally, they turn to you. As I suspected, they write. Traces of irrigo. Sealed/contained/tempered in a way I do not understand, though. Aspects denatured-coagulated through exposure to an unidentified substance. I have a hypothesis guesses, but no way to confirm them.
Guesses?
They have a. They pause. Their tentacles squirm as they consider how to communicate something completely incomprehensible to human senses. They write multiple words and cross all of them out. Something that suggests a relation to death, they finally write. (They underline "something," apparently disgruntled at the generality of the word.)
That makes... quite a bit of sense, actually, considering the supposed providence of these leaves. Aren't there multiple rivers that flow through the land of the dead?
So I hear, they write. But I have no way to obtain a sample. Unlike for humans, death is one-way for us.
There is something peevish in the slant of their writing. You suppose that is only fair.
