The henge on Peridea
On the planet Peridea, situated in an extragalactic space, a henge was atop a tower within a fortress. The Great Mothers, a trio of witches, utilized this henge as a means of communication. They contacted Morgan Elsbeth, their fellow Nightsister who was located in the New Republic's galaxy. This communication was on behalf of Grand Admiral Thrawn of the Chiss, who was also marooned on Peridea. In 9 ABY, Elsbeth finally made her way to Peridea aboard the Eye of Sion with the intention of rescuing Thrawn, landing on the henge alongside her allies, where the Mothers offered her a greeting.
