Kinda, basically, yeah? At the beginning of the world - and in every other world in my universe, for that matter - there's a feud between a dark lord and a dragon god. In ours the dark lord's the source of all negative emotions, demons and black magic, and the dragon god couldn't defeat him. Shabranigdo was then split into seven pieces and reincarnated into human souls, and every reincarnation cycle is supposed to weaken the piece until there's nothing left.
Something similar happened to the dragon god Ceiphied. My sister was born with a fragment of a dragon god's soul, so she's crazy powerful, and if ever gets memories of that I will probably end up moving to a different planet.
