Maker of Kaylab Lennox and a High Inquisitor of The Coucil's midwest region, Acillius served under both Gaius Marius and Sulla between 80 and 90 BCE(BC). He is driven by power and control and believes that "the ends justify the means". While he is notorious for throwing his weight around, he is still regarded as fair. Acillius recurs throughout the Odeum series and plays a major role in its events.
