Ganthel

Ganthel is listed as Rae Sloane's birthworld: a developed world that produced an Imperial officer who survived Endor, Jakku, and the long walk toward the Unknown Regions. Aftermath and Ahsoka-era references keep Sloane in the file; the planet is the footnote people suddenly want.

There is no famous battle here in the current record. The dossier exists because Grand Admiral Sloane does, and the catalog already names this world.
