Darksphere

The Dark Orb is a special item that appears in Fire Emblem: Monshō no Nazo. It was one of five orbs possessed by the Divine Dragon clan and used to complete the Shield of Seals. By itself, it possesses the power to control minds, such as by controlling the enemy to stop them from fighting the user. However, it magnifies human emotions, making it very dangerous for humans to use. Gharnef created the Imhullu spell from the Dark God. After his defeat, he handed the Dark Orb to Hardin, which corrupted him.
