My new oc rp idea

So I was thinking last night "what if the elements of harmony didnt exist hoặc were destroyed? Would there need to be new ones created hoặc would Equestria fall into chaos?" So this is the idea, ngọn lửa, chữa cháy dash(my oc) has came down to find ponies to come with him on a quest to find.....THE ARCHIVE! To find out how the elements were created, they will encounter danger, like the changelings, nightmare moon and discord

So how does it sound?
