Arriving on a new planet, the team meets with the Alteri, a martial society that practices ritual combat. After getting defeated several times, Stacey learns their ways and that wearing the ""Mandro stones"" enhances the wearer. As she dons them she begins to suffer strange side effects - paranoia, anger, addictive qualities, and physical transformation. Stacey goes berserk and escapes for the Stargate. The team manages to slow her down enough so Gus can talk her down and Draga can transform her back to normal. Meanwhile, Draga has a vision of a star system after touching the stones which they believe may be the home of the Ancients.
