You guys, Yamino worked so hard on this page!
Thronum Mare is based off Mt. Saint-Michel, but of course Mt. Saint-Michel doesn't have Thronum Mare's walls, nor its large population and certainly not all its buildings. Imagine drawing all those roofs?! They were subsequently colored in by myself (Laura), and Yamino added that beautiful final shine.
I would swim in that ocean, wouldn't y'all?
