The Crown and the Throne - Imagery associated with Sora

[jbmasta 67]

One thing that I've seen in lots of places, but has never had an obvious or given explanation (unless I've missed the bleedin' obvious) is the symbolism behind Sora's crown pendent as well as the recurring image of him on a throne. Sora's crown pendent has been an aspect of his costume as a teenager across nearly all his outfit variations, even in the Pridelands when he was turned into a lion cub (although, curiously, not in his merboy form), but there's no backstory behind it, no explanation for how he received it (he isn't wearing it as a four year old in Birth by Sleep), nor the significance to Sora. Sora's parents have barely had more than a mention and a single line off-screen. His father is mentioned in Birth by Sleep by Riku, having taken them to the island and of course his mother is still sitting at that table waiting for all we know. There's been nothing to even hint at a lineage in royalty.

If Ventus is somehow an influence, he too has had nothing to indicate he has a royal background either. In Union Cross he remarks he was surprised Ava approached him to join and lead the Dandelions as he wasn't anyone special or a high ranker. He doesn't come off as an aristocrat or nobleman. The Age of Fairytales doesn't indicate the social structure beyond the Unions and the Foretellers. There could be a monarchy, aristocracy or democracy for all we know.

Additionally there's the fact that in Kingdom Hearts 2, when Sora unlocks the Paths in Between, he's standing on a huge crown symbol, much like when he sends the final strike at Xehanort in Kingdom Hearts 3. Again, the symbolism is never made clear and no one else shows this with their own symbol. It's not conclusive since only Sora is seen unlocking these paths, as Eraqus opened up the Lanes In Between for Terra and Aqua in Birth by Sleep so they could investigate the Unversed, at least the lanes to Castle of Dreams, Dwarf Woodlands and Enchanted Dominion as well as the Mirage Arena.

For something that's right in front of our eyes, it's something I've never seen remarked up for its meaning.

I think the crown is just symbolic of his role in destiny. Riku also has a crown associated with him, because Oblivion has a crown on it and is associated with him. I think the trio are all royalty. Kairi is the princess(maybe even queen eventually) of Heart. Riku is the Dark King(because oblivion has a black crown) and Sora is the inbetween light and dark. He gets a silver crown because he is a grey king.
