The prince of Griffinvale married a poor girl against his father's wishes. The king sent him away on a crusade and drove the wife out of the castle in his absence—expecting the prince would forget her in time. He died in battle instead. The wife bore a child and died in confinement. The king, left without an heir and consumed by grief, sank into mourning while his court filled with ambition and conspiracy. A group loyal to the fallen prince hid the heir from everyone. Now royal knight Edmund Ulmer has been tasked with finding the child and restoring them to the throne of Griffinvale. King's Heir: Rise to the Throne is a hidden object adventure game developed by Game-Owl.
