The group known as the Infernal Council comprised Sith Purebloods who were once enslaved by Soa many years before the rise of the Galactic Republic. They were held in stasis alongside him within the Eternity Vault located on Belsavis.
After a strike team infiltrated the Eternity Vault, these warriors were freed. The strike team subsequently engaged them in a series of individual combats, resulting in the death of every council member.
The council's composition included several Sith Purebloods:
- Doruk the Uncaged [1]
- Alarii , Sister of Sorrow [1]
