The first book of The Overlords series is titled Legend of the Treasure.  In this book, our heroes set out in search of the fabled Treasure of the Land.  The following can be found on the back cover of the book:

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?

The leader of the group is Marcus Braxton, a seasoned fighter who has yearned his whole life to find the Treasure.  The town elders of Aegeus allowed him to put together a team of adventurers that would help him on his quest.  They are Harrison Cross, a young, talented paladin, Xavier Murdock, one of the finest bowmen in the land, Pondle, a halfling thief, Jason Sands, a strong an seasoned warrior, Aidan Hunter, an expert tracker, and Swinkle, a young and gifted cleric.  Together, they hope to bring back to Aegeus the hoard of the ancient Four Kings, enough treasure to help every man, woman, and child in their part of the land.
