Now I do wonder, honestly, how ownership rights go here. Obviously they werent created by locals off the yucatan peninsula, so they cant proclaim it is their property. And since somebody made them, that means they may have an original owner kicking about, which may mess up the salvage claims of either sydney OR whichever nation has claim over the precise spot of the reef. After all, there have been plenty of stories about artifacts being returned to even the descendants of their previous owners after having been taken or lost. The fact the orbs have bonded with sydney and cant be left behind also creates its own legal quagmire. For all we know its like a transplanted organ, no, you cant take it back, even if you were the original donator.
