The Cyber Chronicles VII: Sabre

When Tassin and Sabre finally reach Omega Five, they discover that four years have passed there, and her cousin, Dellon, is now King of Arlin. With no allies other than the young King Sharmian, ruler of the smallest kingdom, Mandor, and Torrian’s puppet, Sabre is once again Tassin’s only way to regain her throne, and he must pit his skills against medieval knights in a bid to win back her crown.
