Phoenix Logs/The Ark/Halo


 * A Halo is an artificial, planet-sized ringworld weapon, created by the ancient
 * Forerunner race as a weapon to combat the parasitic entity known as the
 * Flood.


 * Despite millennia of scientific and philosophical advancements, the Forerunners
 * were unable to stop the spread of the Flood as it propagated across numerous
 * life-forms through infection. After many defeats, the only answer was to starve
 * the Flood by denying its ability to infect anything - by destroying all sentient
 * life.


 * The Ark was built to construct, maintain and activate the ringworlds that make
 * up the Halo Array weapon, and seven ringworlds were launched at strategic
 * points across the galaxy. The Halo Array was fired, wiping out all sentient life
 * without damaging the inhabitants worlds and the Flood retreated.


 * However, towards the end of the Human-Covenant War, the Halo Array once
 * again became an ever present menace, the weapon to end all wars.
