The Brightstar Pact is an alliance of non-aggression and mutual protection between several powers of the Kasperion Sector. It began with a peace treaty between the Hexarian Star Republic and the newly-formed New Alliance at the uninhabited , near the edge of HSR space. The two peoples agreed to put behind them the earlier clashes (attributed to the earlier Eprise Alliance). In time, this relationship strengthened to an agreement for mutual protection in the event of critical threats to their sovreignty.
