Aerth is more skilled at subtle changes, though his power is used most effectively in strong bursts. Like a frog that doesn't realize it is boiling as you turn up the heat, Aerth can subtly change the air pressure in an enclosed space. With no wind to shift , this can be done completely undetected and without his needing to so much as lift a finger. While he isn't powerful enough to make the air heavy enough to crush things like the atmosphere on Venus, he -can- change the pressure enough that the simple opening of a door elsewhere in a building can trigger an air-burst explosion. If a place is sealed, he could potentially kill someone by making their blood vessels burst from the psi, though he'd have to be in that room with them, thus putting himself at risk. It is only small sealed containers that he can burst at a distance; his power is mostly localized around his person.

This is a silhouette icon by  Jasmae, as a sort of bonus for participating in her character sale. I kind of needed one for Aerth, since he is technically my fursona.

Aerth is my own character.
