Now that dragon skull your girlfriend had touched had belongeged
not
to a female dragon goddess
but the female avatar of a female dragon goddess
and the throne and stuff had belonged to this avatar
So your foolish girlfriend had wished for another female avatar of this female dragon goddess to come into existence so your girlfriend to gaze apon her
Due to Divine Rules
your girlfriend could not be this
female avatar but she could serve as the
Mother of the Dragoness
which was what had happened
It turned out
you had been chosen to be the
New Dragoness Avatar
and you reawakened from your deitified transformation as a
female dragon perched on the throne in the Ruined Castle
with yoir now human girlfriend having second thoughts on the matter
