From Destinypedia, the Destiny wiki
According to Xûr, the Jovians were once human, but were radically transformed to a far greater extent than even the Awoken; the Nine themselves are implied to be responsible for this change. Additionally, Xûr claims that while the Awoken had no choice in being changed, the Jovians did have a choice. He speaks of being made of cells with the memories of the past, and coming from the dust. The Light can cause pain to him.
