The Shattered Star
The Sihedron, or Shattered Star, is sundered into seven shards, each made of a different Skymetal. If these shards are rebuilt, its full abilities may be discovered.
However, each shard carries a curse related to its associated sin. The curse may be suppressed by placing a specific type of ioun stone in the appropriate spot of the shard. Additionally, the magic effects of each shard are so strong that carrying more than two causes problems such as becoming nauseated.
