ランス IV　－教団の遺産－

Following the events of Rance III, Rance is sent to Ylapu, a giant island floating above Leazas. There, Rance must find a way to return to The Continent's surface, while being hindered by agents from Helman who are attempting to revive and control the Wargod Upsilon, an ancient superweapon created by the Holy Magic Sect.
