Events
- The 20 Parsec Limit was established following the loss of the Far Spinward Colonies in 2110 and the failure of several missions to reestablish contact. As a result, any colony worlds more than twenty parsecs from the Sol System were left to their own devices.
- The Concordat mission to the Hyades Cluster discovered several resource–rich worlds for Hyperdyne Systems. Unwilling to relinquish such a valuable asset, Hyperdyne defied the 20 Parsec Limit to supply and support mining operations in the Cluster.
