Keeping my tinfoil hat on, the Enigmatic Maiden's color palette of white, gold, and blue along with the strange winged device on her hip are reminiscent of FFXII's Ultima, as the title of "maiden" is also the same for Virgo, Ultima's zodiac.

Back to reality, the FFIX-looking abandoned village at the foot of Solution Nine in Heritage Found is interesting, doublely so that they weren't allowed to talk about it. It's much more generic fantasy looking, as is the Enigmatic Maiden's attire, minus the green tron lines on her shoes. Solution Nine is to no one's surprise, looking to be the lost city of "gold" and it's interesting they mentioned people living forever carefree. Maybe it's possible it's a server like people had said before?

Tangentially related to Solution Nine, it seems that railroad tracks lead up to it in the new trailer through a tunnel, and unrelated to anything else, the "Bar" sign in Shaaloani appears to have changed since the original Shaaloani trailer to now say "Saloon". Back to Solution Nine, there are two new "Bar" signs in proto-alphabet and another sign that says "Owen" next to the companion cube-looking thing? Gonna need a second opinion on that one.
