Ar'krai (also spelled ar'kai) was a state of genocidal war among the Bothans. The basic tenets of ar'krai state that if it was declared, all fit Bothans—and usually those that weren't—were required to volunteer for military service against an enemy that threatened the Bothans with extinction—and the Bothans were to repay the enemy in kind. The enemy was to be destroyed to the last individual in an act of speciecide, their name be wiped from history, and their homeworld be ground to dust. In recorded Bothan history, ar'krai was declared only three times. The third was during the Yuuzhan Vong War, after the Battle of Coruscant and the sacrifice of the Bothan Borsk Fey'lya, Chief of State of the New Republic.
