Harrison Cross wishes nothing more than to help his hometown of Aegeus secure the land's most sacred treasure, the bounty of the ancient Overlords known simply as the Treasure of the Land. The original Overlords vanished on one infamous day over 1,000 years ago leaving behind clues to their hidden treasure in the form of indestructible metallic plates and a map revealing a series of secret rooms. During their journey, Harrison and his friends face countless foes on their way to the sacred Seven Rooms, including the evil Scynthians who want nothing more than to eradicate the human race, and the ruthless and treasure-seeking Lord Nigel Hammer, governor of Concur and his large menacing army. Using the clues discovered along the way, the group must successfully navigate through the hidden mysteries of the sacred Seven Rooms in order to secure the land's most elusive prize. Only then will their journey be a success. The question is, will they succeed?
