Lumar

Lumar, according to Isaac, is the world - different from those of which readers are aware - where the aethers define life, as noted in the postscript of Tress of the Emerald Sea.Secret Project #1 Reveal and Livestream, 3/3/22 It is somewhat of a "backwater" planet.
==Characteristics==
Its twelve moons* are home to a unique strain of said aethers.
==Speculation==
*According to one reader, other readers can figure out how far the moons are from Lumar with the fact that when Tress sails across the border between two oceans, she sees one moon rising and the other setting. That gives readers a very narrow range for the orbital distance of the moons (1.05 to 1.1 times the planet's radius - measured from the center of the planet to the center of the moon).
At that distance, the gravitational pull of the planet would be much stronger than the pull from the moons, even if one was on top of them. Barring magic, one could walk around the curve of the moon, slip off, and fall to the planet.
This means that the moons aren't launching spores at the planet. Instead, the aethers just have to let go and and allow the spores to trickle down.r/Cosmere fun fact, 3/22/23
