Shiwana are spirits of the gusting wind, angry creatures of weather who were once holy people. They create drought instead of rain, due to their resentment of all living things. At will, a shiwana can stop a rainstorm or make standing snow vanish in moments.

Shiwana are usually invisible, but they can also appear as swirling clouds of dust if they choose. Sometimes they help a few living things if this gives them a chance to harm more creatures later on.
