The Obsidian Eye is a black glass sphere about the same size as a normal eyeball. An iris and pupil, inlaid with silver and lapis, are carved on one side. On examination the eye radiates an aura of Black Order magic, but otherwise appears inert.
The Eye has no power unless it is used to replace the missing eye of a living Keldian. When inserted into an eye socket in this way the Eye bonds with its new owner, and cannot be removed without injury. When implanted the lapis pupil widens, and appears to glow with a faint blue radiance as long as the eye is open.
The bearer of the Eye has their vision altered to reveal hidden or magical things. They gain the Passing Gift and +4 Observation at all times, and have a chance to notice hidden items, concealed doors, and the like even when not actively searching. (Make an unresisted roll of Intelligence + Observation -5).
In addition, by concentrating, they can see the flows of magic that move through the world, which appear as networks of luminescent blue lines. By following these flows they can detect active and passive spells, find magical items, or use Tracking to follow the traces of recently cast spells back to their caster. A roll of Int + Sorcery will allow them to locate an area in which magical flows are stronger (spells get a free power level) or weaker (+1 Channelling) if one is nearby. Using the eye in this way is taxing, inflicting one fatigue for every 10 minutes of use.
The final power of the Eye is the most potent, and also the most dangerous for the bearer. By looking another person directly in the eye (and taking a point of Lethal Damage) they may see into their mind and soul, discovering the most important secret that the target wishes to hide at the moment of contact. The target can resist the gaze by winning a contest of Presence versus Will (each attempt takes one combat round). If immediately revealed this secret instantly inflicts 6 Social Damage. Alternatively it may be held back for other purposes. The target of this power is always aware that their mind has been plundered, and conceives an instant hatred for the Eye bearer, and a desire to own the Eye. If they can cut the eye from the bearer's head and place it into their own, then all secrets taken from them are instantly forgotten by all who heard them.
