Sun Sprites are an army of Sun Warriors commanded only by Max. They are a gift from his father Apollo to help save the camp from Typhon's invasion. There is 5,000 of them in a single legion, and they currently inhabit the garage/barracks at Pallas Phoebus. They all look exactly the same except that certain ranks have different colored sash-like stripes. When they choose to, they can dissolve into light.
The overall legion commander. The post was usually filled by a senator, appointed by the emperor, who held command for 3 or 4 years, although he could serve for a much longer period. In a Roman province with only one legion, the legatus was also the provincial governor. In such circumstances, the Legatus was dual-hatted as both Legion Legate and Imperial Legate. The Legion Legate also served as commander of the Auxiliary units attached to the legion though they were not formally a part of the legion's command structure.
Named for the broad striped tunic worn by men of senatorial rank, this tribune was appointed by the emperor or the Senate. Though generally quite young and less experienced than the tribuni angusticlavii, he served as second in command of the legion, behind the legate. Because of his age and inexperience he was not the actual second in command in battle, but if the legate died he would take command of the legion. This tribunate was often a first, but optional, step in a young man's senatorial career.
