Aldwin

Aldwin was a member of the Tok'ra who had several dealings with the SGC. During SG-1's mission to rescue Jacob Carter from Ne'tu the Tok'ra High Council orders Aldwin to launch a weapon at the planet's core that would destroy the moon as well as Sokar's Ha'tak in orbit in a chain reaction. However, the plan would also claim the life of SG-1, Martouf and Jacob Carter, and Aldwin realized that the only option is to help SG-1.

Aldwin was later sent to the SGC to verify that after SG-1 Shifu is indeed the supposed Harcesis by using the zatarc-detecting device. Several years later, during the Tok'ra's plan to eliminate the System Lords during their high-level meeting, Aldwin guided SG-17 through the Tok'ra base on Revanna. Aldwin was killed when Zipacna attacked the planet, destroying the Tok'ra base.
