The third episode of Ahsoka sees the search for Ezra Bridger and Grand Admiral Thrawn heating up. Ahsoka Tano and Sabine Wren have left Lothal as master and apprentice, tracking Morgan Elsbeth to the planet Seatos in the Denab system, where the hyperspace transport ring dubbed the Eye of Sion is under construction. Morgan has overseen the construction of this colossal transport in order to reach the distant galaxy where Thrawn is currently in exile. Seatos serves as a point of contact between that galaxy and the main galaxy of the Star Wars saga, hosting several visitors from Ahsoka's new galaxy.
