Roscaelifer is not New Eridu, it's a new City
A different City, different people, and a different culture
And it's ruled by Lady Sunbringer, not Mayor Mayflower
It make sense the theme and direction will be different
And we only seen a fraction of it, it's a teaser that doesn't tell much, so why were judging things so fast?
It's interesting seeing the world and lore be expanded upon more, and people need to wait to see the full picture and the story unfolds before judging
