Rance VI: The Collapse of Zeth

Backstory
After offending a high-ranked magic user in the kingdom of Zeth, Rance was ironically thrown into the slave camp while his magic-using slave Sill was treated as an VIP. Vowing vengeance, Rance joined up with an underground resistance group determined to overthrow Zeth's government (and be reunited with Sill).
