Alyyra Firni, aka Sting, is a Ventian who was raised on Aivaris and has developed an intense knowledge of chemistry and some martial arts experience. She leads a group of warriors known as the Sentinels. She was once a successful leader in the Warring Clans, fighting with the Aivarians against the Agrak during Quantis' first alliance with the Aivarians, earning a reputation among the greatest generals, along with the battle name Sting for her surgical and chemical tactics, as well as an arch-rivalry with Prince Amon-Thir of Ruke. However, she eventually realized that Quantis, whom the Aivarians supported, was really the bad guy. Unable to convince the Aivarians to leave their powerful ally and unwilling to join her world’s lifelong enemy the Agrak, she underwent the process (which is very formal for Aivaians) to defect from her post, steal a command ship, and lead a team of Aivarians loyal to her away from the Warring Clans to harass Quantis and fight for a better order elsewhere in the galaxy. This team, now known as the Sentinels, has grown into a legally-licensed militia that is accountable to but independent from the Galactic Armada. As Sting, Alyyra remains a formidable fighter in her own right, using her chemistry skills to devise incredible serums and gadgets that, when combined with her fighting style, give Sting a high molarity of lethal force to be reckoned with.
