5 of the 15 members of the Council of Elders come from Stahl. Stahl is the larger of the two moons, and known mostly for its immense and profound libraries that are not only architecturally awe-inspiring, but filled with vast tomes from many worlds. The Elder's from this moon are chosen for their abilities to utilize their knowledge for the betterment of the races and homeworld, and have the wisdom to not waste too much time trying to reach a decision.
Stahl is lovely to visit, visually, but the people who live here are more known for keeping to themselves and being more interested in their research than much else so it doesn't make for a very lively tourist location. Much of the research needed for a great many purposes is conducted on this moon, and the Luminae here take great pride in their achievements.
