Brintooin was a planet in the Outer Rim Territories covered in plains, deserts, swamps, and a few mountains. It was the home base of the Imperial Hammers Elite Armor Unit. After the Battle of Endor, Imperial Governor Thalkuss maintained nominal control of the planet; but he relied on the presence of Colonel Zel Johans, commander of the Hammers, to retain control.
