The I.A.V. Cortez was more than likely a Tohoku-class cruiser that Derrial Book was an officer on, his duty was to over see an event that could possibly end the Unification War, but tragically resulted in the destruction of the I.A.V. Alexander instead, all 4000 crew aboard the Alexander were lost. Book's level of responsibility in the matter of the incident led him to be discharged from the Alliance and forced off the Cortez.
- The name is a reference to Hernan Cortes.
