Thick weather hides everything north of about 41°, its places included. Turn it off to see what lies under it.
The whole painted map is the planet. It's treated as an AuthaGraph map: cut into the four triangles of a tetrahedron and folded into a globe. Nothing is stretched; every region keeps its true area.
The axis is set so the God Wall runs as level as this fold allows: about 44°N on average, wobbling between 19° and 61°. The Hidden North is the cap above it. Kyoto-Zen and HighCastle sit on the equator, on either side of the Titan's Tear, which is the prime meridian.
The wall can't sit higher than that. Its latitude is fixed by how much land lies north of it: the Hidden North is about 18% of the surface, and a ring enclosing that much sits near 40°N. A wall at 50°N would need a Hidden North of about 12%.
The map's printed frame was trimmed off. Where its left and right edges meet, a strip about 9% of the width carries the edges onward, mirrored, so the God Wall closes across the top of it and the sea closes across the bottom. That strip is also what fits the map to AuthaGraph's proportions.
modeled The terrain view’s heights and sea depths are generated, not drawn.
Globe: drag to spin, scroll or pinch to zoom. The map is wrapped smoothly, so the art is warped a little within each triangle.
Faceted: real flat triangles cut from the map, like a paper globe. Nothing is warped inside a facet; more facets make a rounder ball. The four corner points of the tetrahedron are where any fold of this kind crowds together.
AuthaGraph: the sphere is split into four triangles of a tetrahedron and unfolded into a rectangle that tiles in every direction. Every region keeps its true area. This version follows AuthaGraph's method; the original's exact formulas are not published.
