Need ideas for anew story

Hello. I want to create a new story I have I few ideas how to start it but I need more and I need help. I tell you what I have so far and let me know what you people think should happen next if I like it gets put into the story.

So hears what I have a man just fell asleep and he was taken by a god to help her new world and he was remade into a female draconequus foal and given to discord as a little sister. The god wants the human turn draconequus to be the other half of discord. The human well be the new goddess of harmony, order and peace.

Well that is all I have so far let me know what your ideas are.
