The Obsidian Sphere was a quest item in Legacy of Kain: Defiance that was used by Raziel in the chapter Seek Mortanius as he explored Avernus Cathedral in the events of Blood Omen.[Defiance][Defiance/10][Defiance strategy guide]

Sent to Avernus by Vorador in the chapter Find Vorador to search for the Heart of Darkness, Raziel arrived in Avernus Cathedral at the start of Seek Mortanius. Exploring the Cathedral, Raziel found a door at the back of the Cathedral that was sealed by elemental water. Using the Water Reaver to open the door, Raziel found the Earth forge outer chamber within marked with the Earth elemental symbol on the floor with an empty stand in the middle.[Defiance][Defiance/8][Defiance/10][Defiance strategy guide]

Defeating the four Vampire golems that animated as he descended into the chamber, Raziel was able to spawn several Earth platforms which allowed him to jump up to a higher ledge surrounding the room where he could discover the Obsidian Sphere on a similar stand.[Defiance][Defiance/10][Defiance strategy guide]

The item itself was a darkened sphere of black and orange/red material resembling volcanic rock.[Defiance][Defiance/10]

Recovering the sphere and taking it down to the lower stand, Raziel could place the orb there and this activated the item, powering the nearby warp gate which led to the Earth forge within the Vampire Citadel.[Defiance][Defiance/10][Defiance strategy guide]
