Duskmoth is the mother of Trushfall. She was a brave and loyal warrior but something made her bitter and hate her clan. Together with her mate and son they attacked the clan. They were exiled. She looked for refuge under a tree but a lightning bolt struck the tree. She died. Duskmoth didnt end up in starclan or the dark forest. She wasnt that evil but neighter that good. So she was stuck as a ghost on clan territory, as her punishment.
