Valerium Gas

A colorless, odorless chemical agent deployed in the Correction Centre’s Induction Therapy Section to incapacitate and condition new prisoners. Bisham describes it as lethal in precise doses, causing unendurable pain when combined with brain sensitization programming. The Doctor first experiences its effects—ragged breathing and vocal strain—immediately upon waking strapped to the induction chair.

After: Still active in the chamber, continuing to affect sensory perception
