Tyndall was an Unallied planet. The world first conquered by the Thinking Machines in 181 BG along with Bellos. It was later freed by the Army of the Jihad in 178 BG. Whether it joined the League of Nobles it's not known. A refugee from Tyndall asked Ginaz Swordmaster Jool Noret to teach them so he may destroy many machines. Nooret replied no, but allowed that refugee and any other to watch and learn what they can, for Noret would not take any students.
