Cask of Frozen Dreams

Wondrous item, artifact

An ancient elven artifact, the cask is an ithilnaur box 2 feet long and 1 foot wide and tall with elaborate scrollwork and filigree. Within lies the stored remains of every dream that has ever been dreamed and every memory that anyone has ever had. When used together with the Dreaming Stone, it has virtually all information.

That said, the information is almost impossible to access easily. Without divine help it would take many years to sift through all the dreams and memories to find the information one seeks.
