If you’ve ever fought with a sibling, you know how torrential those contests can be. Of course if you and your sib happen to be Incan gods, the fallout can be considerably more dramatic. Take, for example, the case of Illapa, the sling-toting god of stormy weather, who according to one legend would taunt his sister, the Milky Way, by taking aim at her water pot—the cracking of which produced rain and thunder.

This legend brought to you by the folks over at godchecker.com, who also claim that a surefire way to end a drought is to tie up a black dog until he’s practically dying of thirst, at which point Illapa—apparently a great canine-enthusiast—will send rain out of pity for the creature.
