There's an interesting thread going on about weather and several ideas are floating about on other aspects of looking down at the map. But what about looking up?
I've seen nothing yet about a moon or moons, constellations, or any other astrological sort of stuff. These things have all kinds of potential as part of magical systems. Each shard type could be associated with a moon, or a single moon (and the sun) could move through a zodiac of 2 or 3 signs for each Element, with slight benefits or penalties for a given magic type depending on the chart for the day. A moon or moons also could be off-map destinations for working major magic.
And yes, I said in another thread that I really hope the world of Elemental is not a "realistic" planet, but some non-sphere thing. In a fantasy setting, there's no conflict between that and an astrological system of some sort.
