doflamingo answered the question of his connection to the celestial dragons, with “it’s much more rooted than that”
the truth is, doflamingo is a shandorian and he is a descendent of the kindogm of jaya, where norland visited.
this mean doflamingo is the man who knows the ancient warship’s location and he can in fact, read the poneglyphs.
this explain why bellamy travelled to skypia and retrieved the golden pillar for doflamingo. this also explains why doflamigo is always wearing that feathered coat, to hide his wings, thats how he flies!
Now to the rest of my theory:
jaya is the golden city and land of dwarves told of in norland’s adventures. when norland told the king of his home country about the island upon his return, the king organised an expedition to the island in order to take all its gold.
upon returning to the island half of it was missing – the half were all the gold resided. norland was called a liar and exceucted back in home county. the missing parts of the island had been shot up into the white-white-stream also known as the ‘sky ocean’ and became what are called the sky islands.
specifically the larger chunk of jaya became known as skypia. before jaya was slit in two it had the shape of a skull. if you look at the shape of dressrosa and green bit along with the distance between them, you will notice they somewhat resemble the two eye-holes of the jaya skull.
how did they end up in the other half of the ocean? these may have been taken in by the white-white-stream and ended up falling in to the new world’s sea.
The most sublte hint to prove accuracy given is Bellamy travelling to skypia to retrieve a golden pillar for doflamingo. Also the dwarves themselve’s spoke of norland yet they are on green bit, yet their home was jaya and they weren’t on skypia.
the shandorians worshipped the ancient weapon pluton and guarded the poneglyphs. norland’s story occurred 400 years ago, doflamingo being king of dressorosa likely means he is a royal descendent of the shandorians who ruled the kingdom of jaya before it was affected by the knock-up stream.
doflamingo’s connection to the ancient weapon would explain his influence over the world government and why he is dubbed the most dangerous man in the world.
22 years ago the scientists of Ohara where exterminated by the world government, this is around the same time Doflamingo joined the shichibukai.
I believe the reason for this was that doflamingo offered his knowledge of pluton and the poneglyphs in exchange for his position within the shichibukai/wg thus the world government no longer needed the scientists of ohara.
