Looking for a replacement from another forge, Kain found his way to the usual portal rooms in the forge, but these were blocked by a sealed door which he opened by recovering the Earth Globe. Beyond he found portals to the Dark Forge and progressed through the forge to the portal rooms there where he found a warp to the Water forge which had collapsed into ruin - its surrounding devices were still present however, including an exposed Sphere of Energy which Kain could recover.[Defiance][Defiance/9][Defiance strategy guide]
The Sphere itself was simply a pink and purple patterned globe which glowed with ripples of energy.[Defiance][Defiance/9]
Returning to the Earth Forge, Kain was able to place the Sphere of Energy into the holder nearby the Air Forge portal and this powered the device allowing the Warp gate to become functional. Passing through the warp, Kain was able to progress through the Air Forge on his way to discovering the Timefragment of the Balance Emblem and the Time Reaver in the Light forge.[Defiance][Defiance/9][Defiance strategy guide]
Notes[]
The Sphere of Energy is explicitly named as such in the inventory and its name is reiterated in the official guide - although in dialogue Kain simply refers to it as an "orb".[Defiance][Defiance/9][Defiance strategy guide] The artifact is labelled in game files as "cit_artifact_three" and its final holder is listed as "cit_lock_three". Other working spheres share a virtually identical texture set - these are labelled as "portal_pylon" and "portal_pylon_inert".[Defiance][Defiance/7][Defiance/9]
The mechanisms of the Warp gates including the Sphere of Energy are detailed in concept art and in Bonus materials, where the gates are referred to as "portals", the sphere as an "orb" and the pedestals as "orb holders".[Defiance]
