Phoenix Logs/Forerunner/Protector Sentinel


 * Forerunner defense constructs controlled by Professor Anders.


 * Exclusive to Professor Anders, the Protector Sentinel is a flying Forerunner
 * drone armed with an energy-based sentinel beam that is effective against all
 * enemies. It can be upgraded to a sentinel swarm, which adds smaller Aggressor
 * drones as an escort. Sentinels explode in an EMP blast upon death, stunning
 * nearby enemy vehicles.


 * Professor Anders has shown a remarkable ability to manipulate Forerunner
 * command codes and bypass directive locks, giving her the ability to bind the
 * Ark's own defense constructs to her will. The full extent of her capabilities have
 * yet to be tested, as the Professor's attention is constantly diverted to more
 * pressing needs like finding a way home.
