Steve’s character from our Changeling: the Lost games.
Sonata is a darkling, he stuggles to keep his form together appearing as a whisp, with streamers of smoke flowing from his body. Sonata can keep his form easier in the dark, while sunlight and moonlight fade his form and cause him to almost disintegrate before your eyes. Sonata spends his time busking when not hiding from the sunlight in an abandoned warehouse he and Freki occupy. Sonata was originally a creole jazz musician who fell on hard times due to his increasing dependance on narcotics. Eventually he was found dying in a gutter from his latest overdose, and was stolen away by the fae and doomed to uncountable years trapped in a world of nothingness, no light, no sound, no heat. Eventually he escaped through the hedge into venice, where he was found by other changelings who came to his aid.
