3) The vagabond is not a dragon

As much as people argue that "The Vagabond" is a dragon. He fails to meet the requirements to be a dragon. First off, he is from a foreign land and does not associate with any of the clans. The other 9dragons gold are all highly ranked in their respective clans and were chosen to represent their clan or forced to represent their clan. By using this condition, he fails to meet the requirement to be one of the 9dragons gold. Second, "The Vagabond" did not partcipate in the duel of the nine dragons. As much as there is argument for it, he could not have been a part of it because he had no clan to represent. The tablet was also broken into nine pieces, one for each clan and although the Thunder Emperor did not participate, the Black 9 Dragons Gold is still one of the clans and none of the official story contributes to the fact that "The Vagabond" actually participated in the duel. As mentioned in the story, there were NINE pieces of the tablet ("The Vagabond" would have been the tenth), the EIGHT Dragons (not 9, the 9th would have been the Thunder Emperor but he did not show up) drank the elixir, the EIGHT Dragons entered the field, and the EIGHT Dragons participated in the duel. Should "The Vagabond" have participated, there should be NINE Dragons stepping foward, NINE Dragons drinking the elixir, and TEN pieces of the tablet. The point of the duel was to shut the doors to disciples for the clans that lost so that one clan would remain superior and defeat the other ones who were not allowed to recruit new disciples through numbers.
