Absolute drivel, no relevance to dragons and you don't even mention them in your post. If you're referring to the actual god Osiris then that is Egyptian mythology which is totally different from Greek. I assume by falcon you mean Ra, his relationship with Ra is in dispute, as some believe they are either not related at all or Ra is the father of Osiris. No idea where this 'world egg' thing has come from but Egyptian mythology dictates that earth was created from an infinite body of water by a few gods shaping it from their own beings. The only way dragons could be brought into destiny is if they introduced Ahamkara's which would be absoloutely amazing.
