Well, Is there? What if the red priests translation of the prophecy, that the saviour will be the 'lords chosen' this lord being the lord of light, was incorrect as Aerio Onos is lord of light and Aeksio Ondos is goldenhand. There are only a few characters with golden hands. Jaime Lannister is the obvious choice for being 'golden hand'. Olenna Tyrell has Gardener coins with golden hands minted on them. But the most desirable choice of the 'golden hand' is being golden hand is the baker's boy from Kings Landing. He browns bread with golden butter. Now who would be his champion?
