Phoenix Logs/Forerunner/Forerunner Control Tower


 * Multi-purpose control structures


 * As the Ark's name suggests, it was designed to play host to an incredible
 * variety of life collected from across the galaxy. This almost inconceivable volume
 * of biodiversity necessitated a flexible environmental system on the Ark as the
 * Forerunners prepared for the galactic reseeding of life after the Halo Array was
 * activated.


 * On a practical level this meant that all habitable surface area on the Ark could
 * be covered in an environment to match any life-sustaining planet in the galaxy.


 * Atmospheres, soil and vegetation makeups, bodies of water or other liquids,
 * and even gravitational conditions could be custom-set in areas as large or as
 * small as needed to sustain collected specimens from a particular planet.


 * These environmental settings were accomplished through a network of Control
 * Towers. These towers worked essentially like the output nodes of modern
 * mass-particle replicators or the archaic 3D printers of the 22nd century,
 * generating kilometers-deep environments around them through manipulation
 * of raw materials stored deep within the superstructure of the Ark. The base of
 * each tower then generated desired gravitational conditions.


 * When an environment was complete, only a small percentage of each Control
 * Tower remained visible above ground in order to minimize interference with the
 * new local wildlife while still allowing for data gathering on the surrounding area.


 * Today, these Control Towers lie mostly dormant. But with new visitors to the
 * Ark and the possibility of new uses for the Ark's scientific and military
 * capabilities, the towers offer literally world-building power to whoever controls
 * this ancient installation.
