Shard of Being

The universal cosmic power needed to bring to life the very physical and metaphysical existence of a world can only be done by that of a deity group of significant power or in Toril's case, a single Overgod named Ao. During his creation of Toril, the awesome power he used had fragments become crystalized. These crystalized shards held very strong and powerful magic in it that allowed to ascend items that were crafted with it into awesome artifacts of power. The shards also had other uses but one of the most secret and crucial use was to open the sacred vault where the Book of Creation is known to be found. 
These shards became known by the creatuers of Toril as the Shards of Being. A dormant shard has no power or ability unless it is embedded and crafted into an item. From there, that item holds awesome magical power. That power can also awaken a stronger and more potent magic when the wielder or user of said item has moments of exceptional growth of the heart. It should be known that a shard that has been removed from an awakened item can retain its power and be used as a key to open the vault. The vault has never been opened by anyone but the gods have passed down the knowledge that 12 awakened shards would be required to open the vault. 
Known locations of the shards are not recorded for security and protection.
