Tyndarius is a pyromancer on the Ring of Fire Islands whose dreams were visited by the Queen of Monsters where she gives him the knowledge to form the Firestorm Onslaught. Using what he had learned, Tyndarius forms the Firestorm Onslaught with his army consisting of Armored Tigers, Fire Pikeman, Firestorm Corporals, Firestorm Knights, Firestorm Majors, Firestorm Scouts, Firestorm Tigers, Flame Soldiers, Storm Scouts, and Tiger Cavalries. He is served by Blazebinder, Firestorm General, and Major Thermas. Tyndarius and the Firestorm Onslaught begin their campaign by attacking the different parts of the Ring of Fire Islands. This leads to the players working with Kyron to fight the Firestorm Onslaught.
