Perpetuity Chamber
From Tardis Wiki, the free Doctor Who reference
The Perpetuity Chamber was a prison that holds its captive/captives in stasis forever, until it was reopened. One was protected by Perpetual Pete on Stanalan, which contained Drexxons whom they had trapped because of their violence and aggression. It was opened using a tune played by Garvo who had been controlled by one Drexxon for many years. (NSA: Death Riders)
