Promethean Knight

Promethean Knights are bipedal, autonomous Forerunner defensive constructs. Several legions of Knights represent the central occupying force in the shield world of Requiem, alongside a number of other defense machines.

Overview
The origins of these automatons are both ancient and mysterious. While they differ significantly from the ancient Forerunner Prometheans, a legendary class of Warrior-Servants, they are nonetheless a force to be reckoned with. They are fully weaponized, heavily armored bipedal warriors, easily capable of engaging and terminating perceived threats in almost all environments.

They are known to use Lightrifles and Scattershots as their ranged armament, in addition to a bladed weapon on one hand. They are able to deploy Watcher drones, carried in the back of their armored carapace, for combat support. The Watcher sentinel can greatly improve the Knight's combat capabilities, raising hard light shields or healing the Knight, summoning Crawlers, or flinging back enemy grenades or other ordnance.

A variant of the Knight, known as the Lancer, is capable of teleporting over short distances; this ability allows them to enter the battlefield via teleportation or to quickly retreat during battle. Lancers are also capable of charging at their opponents in a zigzagging motion at an incredible speed. This enables them to make use of the Scattershot's effectiveness in close quarters.

Appearance
They have two sets of arms; two larger ones at each shoulder in which the weapons are mounted and below the shoulders, a comparatively smaller set with small, five-fingered hands. All of their limbs appear to float in place without physical joints. Knights are covered in patterns of light and have a fire-like glow around their heads. The head features an armored helmet with glowing eyes and what appear to be grimacing jaws with rows of teeth. This helmet assembly can be retracted in two sections, revealing a glowing skull underneath.
