Silver-skinned Figure

A silent observer clad in silver-toned skin, moving with deliberate purpose through the derelict vessel’s corridors. This figure neither speaks nor interferes, but watches the Doctor’s actions with detached precision. Their presence suggests a silent sentry, perhaps tied to the ship’s ancient rituals or survival mechanisms—aligned with the Cailleach’s design rather than the Doctor’s intrusion. The silver skin may mark affinity with the vessel’s original inhabitants, now reduced to a solitary guardian in the aftermath of centuries of sacrifice.
