Question: How old is Atlantis? They say king Atlan was in charge at a time when most thought the earth was flat, well that's less than 2000 years ago, however the Sahara has been a desert for a whole lot longer than that and it was said to be home to one of the 7 kingdoms, but them the Karathin says it has guarded the trident for 1000 years, so which is it? 1000, 2000, 10000?
Question: Why did Arthur need to go to Atlantis to meet Vulko? We see Vulko coming to the surface multiple times, would it not have been easier to meet Arthur on land?
