River of Light

River of Light is a variant of the Z-390 incineration cannon.

Overview
This incineration cannon was known to Forerunner Warrior-Servants as the River of Light.

The River of Light was one of the first Incineration cannons ever made. Its core was built and refined over decades by an unknown Promethean who effectively used the weapon and served in dozens of containment operations against the Flood.

After the Domain unraveled, the weapon was originally thought lost. However, it was later found in Promethean cache in a factory that once spun impossible miracles of exotic matter. The forges of this factory were cold and abandoned for a hundred thousand years before the Warden Eternal returned with writs of control, dominance, and resurgence.

While a Promethean Knight can't fully use the weapon's true potential, the artifact’s heart knows its name and purpose, and hungers to be remembered once more by warriors whose hearts pump with life and limbs move with purpose and intent.

In October 2558 a copy of the weapon was located in an area on Genesis that Blue Team passed. The weapon was also used in Warzone simulations by Spartan-IV's.

Gameplay
River of Light is classified as an Ultra Rare REQ and can be summoned in Warzone at Level 7 energy. This weapon will also unleash a long burst of energy blasts if allowed to charge up by holding the firing trigger.

Trivia
This weapon is one of the Special Weapons that could be found in Halo 5: Guardians campaign.
