My new oc rp idea

So I was thinking last night "what if the elements of harmony didnt exist o were destroyed? Would there need to be new ones created o would Equestria fall into chaos?" So this is the idea, fuoco 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?
