Turlough seeks the Black Guardian's power

Turlough is alone in the companionway and pulls out the Black Guardian's crystal. With sailors approaching from above, he desperately attempts to summon the Black Guardian's aid in the hope of altering his fate. The urgency of the moment underscores his desperation; his attempts are interrupted by the crew's presence, raising the stakes as his secret alliance with the Black Guardian threatens to be exposed. This brief ritual captures how far he has fallen under the Black Guardian's corrupting influence.

Desperation gnawing at control, mask of cold pragmatism slipping under pressure

Turlough crouches in the companionway’s shadows, his posture tense and breath shallow as he clutches the glowing violet-and-blue crystal.
