In Heroes of ManaEdit
Joster is a high ranking warrior of Laurent and friends with Alma and Qucas. Princess Minerva has fallen in love with him. Joster is present during several battles to support Roget and his crew, but always as an AI support unit that cannot be controlled by the player.
Joster was the blind King of Laurent and the father of Riesz. His wife, Minerva, died during the birth of Riesz's younger brother, Elliot. Afterwards, he was killed by ninjas from Nevarl, who invaded Laurent on Bigieu's orders.
