The Darksphere (闇のオーブ Yami no ōbu, lit. Dark Orb) is a special item that debuts in Fire Emblem: Mystery of the Emblem. One of five spheres possessed by the Divine Dragon clan, the Darksphere is integral to assembling the complete Shield of Seals, and is positioned in the top-left alcove of the shield. The Darksphere possesses the power of possessing an attacker's mind to protect its holder from all harm, and can only be countered by the Lightsphere, its binary opposite. This sphere is known to corrupt even the noblest of men in both mind and body, a sinister power that is noticeably amplified should its owner be assuaged by negative emotions. This makes it an item that is beyond dangerous for human usage.
