Vessels made with Star God technology are difficult to destroy. When the damage exceeds half of their vitality, they enter a controlled crash. (With high energies involved, engine explosions can happen). Casualties are minimal. It is possible to override these safety measures and fight to the death (like we do), or be destroyed with a single hit that exceeds total vitality of the ship. Crash sites persist for a few days, until the crew is rescued. Ignoring them causes no Infamy loss.
