Apple of Discord

Origins
This is the apple that Eris supposedly used to spawn discord between Athena, Hera, and Aphrodite, which led to the outbreak of the Trojan War.

Appearance
A slightly tarnished golden apple with the term καλλίστῃ still just visible on the surface.

Effects
Whatever the true story, the Apple nonetheless became imbued with the intense discord and chaotic feelings associated with that war. All someone need do is place the Apple near those whom you want to be at war. Once the officials look at and/or touch the Apple, they will be driven to squabble to the point of open warfare. The Apple also emits waves that push those exposed to become suspicious of others and often violent.

Storage
Its power could only be contained by freezing it in a block of Neutralizer held deep within the Dark Vault.
