Past and Present

SG-1 travels to a world named Vyus (P2Q-463) where the people have lost their memories in an event called the "Vorlix" and are in search of their Elders. The "Vorlix" was following a visit from Linea ("The Destroyer of Worlds", "Prisoners"), and they feel responsible for the problems on Vyus. Ke'ra, a young woman with vast knowledge about biochemistry, who assists them to research the world's past, connects strongly with Daniel.
