Many myths and legends surround Umbsol, but separating those that are true from the mere superstitions is a difficult task. They frequent catastrophic events and consume the energy from negative emotions, although what they use it for is unclear.
Folklore holds that seeing Umbsol beneath a lunar eclipse is an omen of ruin. Despite this, it approaches humans only in times of danger, using the light of its golden markings to repel lurking threats.
