Raziel first encountered the Light Forge Key in a side chamber, shortly after passing through the main chamber of the Light Forge, but he found it was protected by a sentry eye. After rearranging some of the Reflectors in the forge, Raziel was able to open several gated doors, enabling him to return to the sentry eye room with the Dark Reaver. Blinding the sentry with the Dark Reaver Raziel was able to recover the Light Forge Key.[Soul Reaver 2][Soul Reaver 2/4][Soul Reaver 2 strategy guide (Prima)]
The Light Forge Key was a golden star shaped artifact and once gained it significantly limited Raziel's abilities - preventing him from Climbing, Gliding, entering Combat, manipulating objects or Devouring Souls. If placed on the ground, the key would quickly return to its point of origin.[Soul Reaver 2][Soul Reaver 2 manual]
Returning the key to the main chamber of the forge, Raziel was able to place the key in front of the large statue, causing the forge to activate and the statue to animate, imbuing the Reaver with Light and gifting Raziel with the Light Reaver.[Soul Reaver 2][Soul Reaver 2/4][Soul Reaver 2 strategy guide (Prima)]
- The Light Forge Key is not named in game, but is referred to as such in the Prima Guide[Soul Reaver 2 strategy guide (Prima)].Game files refer to the object as "ltltkey"[Soul Reaver 2].
- The Light Forge features several subtle star-shaped symbols throughout which hint at the usage and placement of the Light Forge Key. Initially the symbol can be clearly seen in the head of the large statue in the main chamber. Further into the Forge, the star-symbol was seen above the door to the Light Forge Key and the star symbol featured repeatedly along the floor of the trail leading from here to the sentry room where the key was initially found. Returning, Raziel could also use similar depictions of the statue to return to the main chamber.[Soul Reaver 2][Soul Reaver 2/4]
- A far larger mural indicating the fate of the Light Forge Key can be seen on through the Light Forge, featuring a depiction of the statue in the main chamber (in full activation pose) beneath a sun-like image with the same number of points as the Light Forge Key.[Soul Reaver 2][Soul Reaver 2/4]
