Lydia
In the Greyhawk setting of D&D, Lydia is a neutral-good goddess of music, light and knowledge (but hates secrets). She usually manifests as a white-haired woman with bright blue eyes, wearing a robe trimmed with silver and gold, and is worshipped by musicians, bards, sages and famewhores.
Pretty much nothing has been said or done with her since 2000 and Dungeons & Dragons 3rd Edition.
