I am not wed to the terms for the different sorts of aether – feedback?

“There is more that we do not know about the aether than we know.”

Instructor Posvorrem was a tall, lean man, with ice-and-slate braids down to the back of his knees and the tidiest beard his students had ever seen.

“If we were to put all of the knowledge of the aether that scientists currently hold in a goblet.” The instructor picked up the goblet he used for such demonstrations. “Then everything that we still did not know would fill this tower.

“Still.” He had a habit of pacing up and down the rows of tables. It made his students even more nervous than they already were. “We will attempt to cram into your heads all that the goblet holds, and hope there is room enough.”

A nervous titter filled the room. Posvorrem smiled without humor. “Aether is a function of the way parts of the world rub against other parts. For instance, when you have a geological fault line, you will have deposits of the aether that associates itself with stone and earth, mineraloid aether. When you have a deep current in the ocean, the hydrologic aether likewise deposits-“

“How does it deposit in the ocean?”

Instructor Posvorrem coughed. His gaze fixed on the offending student until they blushed and looked away.

“It leaves small pockets of a semi-solid mass which are carried along, sometimes settling at the bottom of the ocean floor and sometimes being pushed to the surface. A wind current will do something similar, and the push and pull of plants in a forest will create small nodules of biologic aether…”

“What about people?” This was, at least, a different student. Posvorrem didn’t even bother looking at that one.

“There is no such thing as humanic aether. I’d suggest you put it out of your mind.”
