The Sword of the First King is a royal treasure of Daventry in King's Quest II: Romancing the Stones. It is the sword belonging to the first king of Daventry. It dates back almost one thousand years and has been passed down from king to king to king since that time. A magnificent clear crystal is embedded within its hilt.
Graham later dislodged the crystal that had been set within the hilt almost a millennium ago. He briefly felt a twinge of guilt, wondering what all the past monarchs of Daventry would say if they saw him damaging ancient crown property. However, this was for a good cause, as Graham used a spell found in an enchanter's lair to turn the crystal into a magical Emerald (unofficial) .
