Phoenix Logs/The Ark/Refugia


 * The Ark was originally created to build Halos, gigantic weapons that wipe out all
 * organic life in order to starve the parasitic Flood of life to infect. This desperate
 * measure conflicted with the Forerunners roles as custodians of the galaxy, and
 * so it was decided that the Ark would also preserve examples of doomed species
 * destroyed by the Halo so they could be reseeded once the Flood had been
 * eradicated.


 * The surface of the Ark was divided up into vast Refugia sections, twelve on the
 * Central Hub and twenty across the large, petal-like Spires that extend out from
 * the center. Each Refugia recreates the environments of common life-supporting
 * worlds and separated by huge walls monitored by Sentinels to protect one
 * ecosystem from polluting another. The Ark monitors and controls weather,
 * temperature and even natural food chains in order to maintain the habitat.
