Audacity

The Audacity was a forrunner vessel used by the Librarian and four other forerunners to explore Path Kethona, also known as the Large Magellanic Cloud, to search for the possible origins of the Flood. The ship was also used during the later stages of the Forerunner-Flood War as the Librarian's personal transport.

It was using this ship that the Librarian traveled from the Greater Ark to Requiem in order to imprison the Didact as a result of his use of the Composer to convert her saved humans on Installation 07 to Prometheans.
