The Sentinel's shield is a Task Force created with one goal in mind. To thwart evil at every turn. Each and every member was handpicked for their specific skill. This squad, though small, is prepared to face any opposition. In the eyes of the men and woman who devote their lives to protection this universe there is no obstacle to great to be overcome.
With Ethan's workshop's destruction he devised a plan for a facility that dwarf's his original station in comparison. Built into the Moon this high tech, state of the art institution has the capability to police not only Earth, but the entire solar system. The track worldwide and can intercept long distance frequencies. The security detection system can pick up on supernatural energies, making stealth approaches practically impossible. The standards of every base exist here as well. , medical wards as well as living space are scattered across the moon base as well as private areas tailored to the officers specific abilities. The teleportation system maybe the most advanced yet, not only covering locations in the galaxy but allowing travel across dimensions and time.
Each part of the facility is coated in a prototype metal developed from both Ethan's armor and his shield. An alloy created through the merging of adamantium, carrondium and an other worldly symbiote protects the walls of the Setinel's Tower from any attack. Beyond this a centimeter thick shield wall provides further strength to the defense bolstering the facility's durability significantly. Multiple power cores use different fuels, rendering EMP strikes useless.
The base doubles as a tourist attraction, with a reserved area for site seeing. There is a biodome that houses a garden filled with plant life from multiple planets, a piece of the moon is covered in a dome which provides oxygen granting tourists the actual feel of walking on the moon without the dangers. There are gravity controlled rides for people of younger ages and a fear inducing freefall system for the thrill seeker types.
The central tower is the team's main operation base, with a super computer system, armory and War Room for discussing mission objectives. The entire base is monitored and ran by AVA, Ethan's private Artificial Intelligence module.
