The Hands that Move the World
The golden disk of Nymm, the sixth moon of Eberron, is most typically associated with royalty. Those born when Nymm is ascendant are said to be sociable and charismatic, gifted orators and con artists. The halflings of House Ghallanda frequently offer discounted rates at their hostelries on nights when “King Nymm” is in its full moon phase.
On its surface, most of Nymm resembles a vast, golden desert. It has an atmosphere which is breathable (with some difficulty), and some sort of subterranean life.
Tandi Warmmantle discovered a large vessel capable of travelling between the moons on Nymm, half-buried in the sand and significantly damaged. It was apparently created by the same race that built Tharkul Kan.
