An orb of light, also known as a Sphere of Light is a magical orb used in Underground Pass quest. The player must destroy four of these orbs in a furnace in order to be able to progress to the next part of the dungeon. Upon destroying each orb it will yield the message, You feel a cold shudder run down your spine as the light of the orb fades.
They were placed in the Underground Pass by the warrior Randas in a failed attempt to ward off the darkness before being destroyed by the player in the Underground Pass quest.
In addition to the item being not bankable, it should be noted that the player cannot hold duplicates of each orb (1-4) and, after the destruction of one of the orbs, the same type can no longer be picked up from its spawn or player-dropped variant. Additionally, the orb spawned cannot be sensed by the Telekinetic Grab spell when hovering over it with the cursor. However, the player-dropped variant can be sensed by the Telekinetic Grab spell, but the spell cannot be used on the orb.
