Azca commanded a cruiser in the Yuuzhan Vong fleet that was approaching the world of Artorias. During its approach, the armada encountered the starship Pythea. Azca ordered his crew to pursue the starship, wishing to capture its crew in order to understand the lifeforms that populated that region of the galaxy and have experiments conducted upon them. The warriors were commanded to conquer the enemy ship but Panha, one of the two explorers aboard the Pythea, rammed the ship into Azca's miid ro'ik cruiser.
