Spontaneous aetheric pocket phonemena was a theory put forth by Italian mathematician by the name of Cappiocra. He developed the theory in the 1860's and postulated that it was likely, if not inevitable, that a combination of specific atmospheric conditions and low-hanging Charybdis currents would cause parts of the lower aetherosphere to break off. These would drift, like weighted pockets of aether, down into the atmosphere.
Cappiocra was an Italian mathematician who was laughed out of Europe and roundly discredited for unsubstantiated theories about the properties of aether. He died in poverty and obscurity.
- "He must make notations on these Cappiocra pockets posthaste. He rather liked Rue's preference for thinking of them as bubbles. Or had he started that codswallop? He might have to rename them such. Altough Tunstell Bubbles didn't sound quite right. he speculated on how they kept cohesion without dispersing into air, as aether ordinarly did. Ambient magnetic charge, perhaps? Some kind of particulated friction indicative of the air over South America?" (Competence, Chapter Nine)
