(Of course, we could also say: "This is fantasy, so we can simply say that gravity stops beyond the atmosphere!" And this is an equally valid approach. The point here is to be consistent in our approach that both the PCs and the invaders have something they can build their plans upon, and real world Newtonian orbital physics have the advantage that they have been studied quite rigorously, so there are unlikely to be any questions that aren't covered already by some article somewhere...)First of all, the existence of the Ring means that the invaders cannot have an orbital presence close to Eberron, because said presence would constantly get bombarded by the Ring. They can descend to Eberron north or south of the ring (which implies that the equatorial regions are the safest from direct landings - the neogi have to fly for a long time to get there), but this uses up energy, so they can't just stay there permenently. Any actual orbit (i.e., an orbital path that doesn't require any energy to maintain) that starts above the hemispheres would quite soon pass through the equatorial plane again. So any orbital headquarters the neogi have would have to be further away from the Ring - an advantage to the defenders, since the neogi cannot stage instantaneous raids from there. As long as the counterattacks of the defenders are quick and they take care to vanish as soon as possible, they have a chance of getting away before reinforcements arrive.Secondly, even the orbital regions beyond the Ring aren't likely to be completely safe of debris. Collisions between objects in the ring will likely send many objects on erratic orbits beyond the equatorial plane. With the rings of Saturn, these are all relatively concentrated on the equatorial region because Saturn is huge and has a huge gravity. Neither is the case with Eberron, so there are probably lots of rogue dragonshards flying around above the hemispheres (with the safest regions being near the poles). This is probably not too much of a risk for most flights through the region, but still real enough that staying there for long times is inadvisable, even if you have the energy to spend...</blockquote>
