Far below the surface, the seafloor is full of thermal vents that pump out great amounts of air bubbles, along with the decomposition process of the spores ). However, the sheer size of the seas makes the incline imperceptible unless one is extremely close to the peak. The surface is uneven - each sea is effectively a pile of sand, highest at the lunagree and lower on the border, where spores of the neighboring seas intermingle. This functions geometrically as twelve pentagons can tesselate the sphere, and due to the shape of the seas and the planet, each sea would border five others, with three around each vertex. Owing to the moons being of equal distance to one another, each sea is of the same size, and roughly the same pentagonal shape. The seas and moons figure heavily in the local language, with many people swearing by the moons or using phrases like "how on the seas". As a result, the entire planet is covered by oceans of aether spores. Įach moon is home to one of the twelve aethers those aethers produce spores, which rain down on Lumar's surface in great, perpetual falls known as lunagrees. This is is called a moonshadow, and is different from a total eclipse. Each day, the sun passes behind one of the twelve moons, leading to the shadow cast from it cooling the land by a few degrees. The planet is surrounded by a set of twelve moons, each hanging in equidistant, geostationary orbits oppressively close to the surface.

Lumar is located in an unknown star system considered a backwater of the cosmere.

Outside of the seethe, the seas are solid enough for people to walk on the surface. By Howard Lyon A ship sporelocked on the Emerald Sea, with the Emerald Moon visible.
