Gradient belongs to AskComboClub, I believe. This OC is based off of him.

Gradient is a NightWing with purplish membrane in his wings. He has telepathy, so there is a silver teardrop scale on the outside of his eye. There is a silver ring on the outside of his eye, kinda like glasses. He is extremely obcessed with scrolls and likes reading with Starflight. He is friends with Eclipse from LoveTheRain.
