Into the Wild Black Yonder.
Ships of the Errant Fleet
After the destruction of the Exploration Fleet Crusis,by the Ark Mechanicus Aes Detrius, the remaining ships jumped to a random vector plotted out in case of emergencies by the Navigatorium Explorata as a ’safety zone". Many ships that fled failed to activate full Geller Fields before transitioning into warp space and where either subsequently destroyed or strayed off course. The remaining ships are known as the Errant Fleet.
Other ships in the fleet are either too small to mention or put simply I am not going to wiki article over 100 ships.
