Kroll's Temple Restraining Planks

Massive wooden planks, roughly hewn and strewn across the stone floor of Kroll's Temple, serve as cruel restraints. Their edges dig into the ankles of captives as they shift—slowly pulling away yet failing to fully release. The planks' rough grain and splintered surfaces contrast with the pristine temple stones, their temporary nature painfully evident as the Doctor and Romana struggle against them. The planks' weight and position prevent escape while allowing just enough movement to prolong suffering, embodying the temple's oppressive design.
