The Turian, Quarian, human war. image - Chris_Rayya

The war between the Turian/volus alliance and the Quarian/Asari Union was long and costly, after loosing every Quarian colony all ships were sent back to defend Rannoch. Over 400 ships were destroyed (Quarian, Asari, and Turian). Rannoch had fallen, but the Turians had lost a stunning amount of ships, leaving the humans to finish off their empire. If not for the Battle Of Rannoch the Turian Hierarchy would have surly won the Human, Quarian, Turian War
