Path Kethona

Known as the Large Magellenic Cloud by humans, Path Kethona was belived by some forerunners to be the source of the flood infection.

After the Didact was imprisoned in his Cryptum for the first time, the Librarian and four other forerunners took the vessel Audacity into Path Kethona to look for a solution to the flood. Instead they found a planet containing primitive forerunners and knowledge of the precursor genocide by the forerunners
