The godling is the illegitimate child of a wayward goddess and her literally star-crossed lover, He of the Expanse. Most beings of madness from beyond the stars are loathsome in the extreme, but He of the Expanse is perversely charming and charismatic enough to have enticed an unholy tryst.
The ladies are arguing about how to get rid of the child, who ended up in their possession after a convoluted adventure on a hidden stairway to the heavens. The flame princess wants to just heave the accursed thing into a river, but the cleric is much more versed in such things and cautions that the bad mojo of killing a godling will surely be their doom.
The godling has, to its credit, developed into a fairly benign entity thus far. Beings in its presence heal 1d6 more hit points than usual each day. Unfortunately, one cannot get inebriated in its presence either, as the magic user come to to realizes in the next few hours.
