The clash on Seatos represents a minor battle during the New Republic Era. It occurred in 9 ABY on the planet Seatos. The combatants were Morgan Elsbeth's forces against a team comprised of the Mandalorian Sabine Wren, the former Jedi Padawan Ahsoka Tano, and the Jedi droid Huyang. The goal of Tano and Wren was to seize a map leading to a pathway to another galaxy. They believed that Imperial Grand Admiral Thrawn and Jedi Ezra Bridger were located within that galaxy. During this conflict, two simultaneous lightsaber duels unfolded: Wren battled Shin Hati, while Tano fought Marrok, the Imperial Inquisitor who had become a mercenary.
Following her victory over Marrok, Tano made her way to a henge on the planet, which served as a mapping device for the other galaxy. There, she engaged in a lightsaber duel with Baylan Skoll, Hati's master. After she briefly disrupted the map and the henge, Skoll caused her to fall off a cliff. This fall resulted in her being transported to the World Between Worlds, a dimension within the Force, ultimately saving her. After Wren disarmed Hati and Hati disappeared, Wren located Skoll at the henge and threatened to destroy the map. Skoll, aware of her desire to locate Bridger, called her bluff, persuading Wren to allow him to reactivate the map so she could accompany them in the search for Bridger.
The Seatos incident was initially depicted in "Part Four: Fallen Jedi," an episode of the Ahsoka series available on Disney+. The name of the incident was later confirmed in "Part Seven: Dreams and Madness".
