Ad Astra Per Arcana
The Elserryn Cluster is a point within the Astral Plane that is packed with stable, two-way color pools leading to virtually every plane in the multiverse, all within a thirty-mile radius. This region is a constant hub of activity and trade, but it is also a mere one hundred miles away from the githyanki city of Vala’Koth, placing it well within their sphere of influence. Several small settlements comprised of folk originating from numerous planes have sprung up here, and ships, originally built for use elsewhere, ply the lanes between them.
Crosswinds Keep is one of the most notable settlements, founded by a former group of adventurers from the Prime.
