Castrovalva
"Let me go!" Adric shouted at the human officers dragging him back towards the radio dish. "The Doctor!"
"Once we retrieve him, he will be looked after."
Adric heard the noise of a TARDIS dematerializing. For a fleeting moment, he thought the Doctor was abandoning him. He turned his head to the noise, letting the guard pull him forward. The Doctor's TARDIS was still behind him. Then he saw the Corinthian column behind him, so out of place in this 20th century Earth landscape.
The Master!
Adric was thrown to the ground as he felt a stab of electricity crashing up his body. He cried out in pain. The others had fallen with him, unconscious. Only his cries sounded across the field.
"Nyssa… Tegan!"
"Be silent, boy," the words cut through him.
Looking up, he saw the murderer. The man took his arm. He was so weak, he could only protest as he was dragged into the other TARDIS.
A hand was at his back, helping him to stand on the metal grating beneath his feet. It guided his hands against a surface like a guardrail. Another hand found the back of his neck. Something cold and wet spilled down his shirt, writhing. Adric shuttered. Cold, probing tendrils found their way across his shoulders, down his spine. He tried to lift his arms to fight, but his hands only gripped the guardrail tighter. He heard laughter, cruel and high. Suddenly, Adric knew nothing but pain. The many tendrils pierced his back as stronger tendrils curled down his arms.
"My creature is penetrating your spine and brain, now."
The words drifted in through the cocoon of pain. He felt the creature's probing ebb, lightening on his skin. Something was pressing against his mind, brushing against his thoughts. Adric flinched, and the creature settled into place.
A buzzing began in his head. It was a stream of numbers. He recognized them from somewhere. His brain caught the rhythm as the noise became louder, unbearable.
"Stop!" he cried out.
More information, more numbers, louder and faster. Used like a machine, his brain willingly continued the rhythm as his mind protested. When it finished, Adric heard the laughter again.
It took him several moments to compose himself before he realized the formulas' purpose.
"Block Transfer… The TARDIS! I've betrayed them!"
"Mm, that's right, my boy. Your own image has flung the TARDIS to Event One: it's death!"
"Doctor!"
"We shall watch his destruction."
"I'll fight you!"
Adric closed his eyes, summoning up the numbers again, another Block Transfer Computation, another Adric. More laughter echoed into his thoughts.
"Is that all you can do? Run off and tell on me? The Doctor is helpless and so are your petty little friends!"
"Now they know! They can stop you."
"They don't know how to operate the TARDIS. Now, show me the terminal room," the Master ordered.
The numbers crept into his thoughts again, unbidden. The image of the TARDIS's control room appeared on the Master's screen. A wild fear overcame Adric. He wanted to hide from his shipmates, hide from the look of horror mirrored on their faces, hide from the terminal blinking the words "Hydrogen Inrush."
Shame darkened his vision, yet the numbers continued. Nyssa flipped the control switch, and the image of the terminal room faded, replaced by the TARDIS in a field of stars. Adric welcomed the dehumanization of their troubles, but he knew it was only a mask to the pain he would cause.
"Now, show me their destruction!"
"No!"
The screen faded to static, as Adric fought against the Master's control. The thing on his back twitched as the Master concentrated his telepathic energy.
"Show me, show me, Adric!"
The glittered remains of the TARDIS exploded across the screen. Adric hung his head.
"We've done it, boy!"
The Master approached Adric. "You've done it, my boy. Now, do you see what we can accomplish? Join me, Adric, and I promise I won't have to hurt you."
Adric remained still, unresponsive to the Master.
Join me, Adric, his voice whispered in his mind.
"I… I will help you. Just don't hurt me again, please."
The Master smiled and turned back to his control panel. Adric found he could stand on his own again, and he removed his hands from the bar. The winding tendrils around his arms tightened, reaching further down.
"Get this thing off me!" Adric demanded.
"Shut your mouth you whining brat!"
Adric glared down at the Master. He attempted to pick the tendril off his right arm, when pain jolted his left wrist. He flipped his hand over; the tendril had pierced his skin and vein. Another jolt, and his right wrist was the same.
"You said you wouldn't hurt me!"
"Dig deep, my pet," the Master whispered.
A wave of dizziness and confusion sent Adric to his knees.
"My creature has sedated you. It will relieve some pain and render you a little more willing."
"But I said I would help…"
"I'm not a fool! My creature tells me you are hiding something from me. Show it to me!"
Adric was no longer in control. He felt the cold metal grate against his face, knew he was on the floor, but no amount of effort could raise him to his feet. It burned through his mind; it knew every thought. It saw the TARDIS, undestroyed.
Adric wanted to close his eyes when he saw the TARDIS on the Master's view screen. Yet even that act of cowardice was beyond him. The Master reached out a hand to him, petting the creature wrapped around his body. It forced its feelings of enjoyment upon him. Adric grunted in protest.
"Take them, my pet, take them to Castrovalva. Let the good Doctor find his rest."
The laughter gave way to the numbers, and Adric closed his eyes.
