The first option the UI presents is Environment. * Such Environments where a League Hall can be built include the Lunar and Undersea environments. The second option is Terrain. * This represents a choice of landscape to build your League Hall in and affects your view from the Observation Room. The final option is the specific location to select, given the previous selections. * Each location has a Prestige cost for both the initial League Hall creation, as well as relocating the League Hall to that location.
