In a time long past, an entire land suffers under the iron fisted rule of the evil Lord Vultare and his sinister queen, The Mannerjay.
Standing against this scourge are the Delta Knights, a secret order dedicated to bringing mankind out of the dark by unearthing the legendary Lost Storehouse, a wondrous arsenal of technology with the power to lead mankind out of the dark ages and into the age of enlightenment.
This magnificent feat is spearheaded by a kindly beggar, Baydool, a Delta Knight. He teaches a bright young slave boy, Tee, the wonders of the writings of the great scientist Archimedes and sends him on a quest to find the Storehouse.
While on his journey Tee meets a young unknown artist, Leonardo de Vinci, who reveals himself as a Delta Knight and a beautiful young servant girl, named Thena. Together they continue their adventure where good battles evil for the future on mankind.
