Yeah, I'm just rolling them out. This was just a little idea that popped into my head after watching 'Parting of the Ways' and 'Fires of Pompeii' back to back. Don't ask me why I did, but I did. There won't be very frequent updates to this one I'm afraid. I have the second and part of the third typed, but I'll see how well people like this one.

Disclaimer: I don't own Doctor Who. Just this story idea, Pheonix Alluk and Wyyv. Not too sure about Prax, but I'll say I own it for now.

Donna glared angrily at the Doctor, arms raised above her head as various tribal weapons had been thrust in her face. As much as she was for seeing new places, she had hoped that the Doctor would know where they were. "Randomizer," he had said, leaning casually against the control console. "Outside those doors could be anything." What was outside those doors was a thick jungle, enveloped in mist and native tribesmen. They had quickly been surrounded and the Doctor's smile he had been wearing when he stepped out of the TARDIS had very quickly disappeared.

The Doctor glanced around at the curious, but armed, tribe of men. He was sure that Donna and himself would either be sent to the chief or sent to a dungeon. Either or. Where were they? The question sprang up suddenly in his mind. He hadn't been able to check the coordinates in the TARDIS because Donna had dragged him out before he could do anything. The setting seemed familiar, with it's thick jungle and swirling mist, the exotic calls of birds in the canopy and the appearance of the tribal villigers. Something seemed to shadow his mind, some strange sense of danger and of warning. A sense of something not-quite-right. As the Doctor was pondering this forbodeing feeling, he failed to realize that the largest villager was speaking.

"...red hair. She might be the Pheonix Alluk. We need to take them to Quetzl and the priest," a smaller villager with a spear leveled at Donna's throat narrowed his eyes.

"What if she is not Alluk, but Wyyv the demon?" The larger villiger smiled, the rubies laid into his shapened teeth glittering.

"Then we shall take delight in their death."

Donna reinforced her glare at the Doctor, mouth open to snap at him about "looking before leaping" (although she wasn't one to talk.) The Doctor knew what was coming, so he put a finger to his lips. She gave a quiet growl instead and followed the moving group of villigers. Donna sent a sideways glance at the Doctor and frowned. He looked a shade or two paler than he normally did, and his brown eyes seemed the tiniest bit bloodshot. Was he sick?

The Doctor knew something was wrong, but he couldn't put his finger on what it was. He felt lightheaded and he could feel Donna's eyes on him. Now he knew he had been to this planet before, but he couldn't remember when (most likely when he was a child) and he still didn't know where he was. Since he figured out he had been there before, the shadow in his mind that told him something was wrong grew stronger. He wanted to grab Donna's hand and run back to the TARDIS, but he knew it wasn't possible without getting impaled by various sharp and poisened weapons. He didn't want to endanger Donna's life, or his own for that manner. So he walked quietly in the middle of the group, into the village.

Bloody preist...If the Doctor hadn't started coughing, they wouldn't have thought I was some demon that had cursed him...Donna thought as she watched the Doctor pace in the stone cell that held them. He had gotten paler, and there were now dark rings around his eyes. She could hear his ragged breathing; whatever was wrong with him was getting worse. She wanted to comfort him, but how? Give him a kiss on the forehead like he was a child? She hardly thought that would work. Instead, she sat on the dirt floor of the cell and continued watching her fevered friend.

The Doctor's head was throbbing painfully. What was wrong? He felt like tearing his head open as he thought the burning question. He felt like he knew what was going on with him, but the answer eluded him, skipping along the edge of his knowledge. Think, think, think... he told himself, Thick jungle, native indians that worship a pheonix, everpresent swirling mist...If only I had some celery to think...

His head snapped up and his hearts sank. He rummaged around in his pockets, fishing for some thing of great importance. Donna raised an eyebrow as he pulled out a stick of celery and held it very delicately in his shaking hands. He let out a strangled sound as the celery slowly changed from a light green to a deep violet. He dropped the celery, ran at the bars holding them hostage and started yelling.

"Let us out! You have to let us out!" Donna stood up and walked over to him, placing a hand on his shoulder as she did. She quickly took it off however, for his body was scorching hot.

"Doctor, what's wrong!" He turned to her, his eyes wide with fear.

"I know where we are," he let out a long haggard cough, "We're on Prax."

"Alright, what's so bad about that?"

"I'm allergic to the gases present in this atmosphere. If we don't get out of here soon, I could die."

Donna thought he was joking at first; after all, how could he be allergic to some gas? The fear in his bloodshot and ringed eyes showed her that he was dead serious. She quickly felt panic build inside her. What would happen to her if he died? He had told her about regeneration, but she didn't believe him. Now, she was faced with the possibility of him dying!

She frantically looked around, looking for anything that could be used to get them out of their prison cell. The guards were standing with their backs to them a few feet away from the cell. Donna grunted in frustration, wanting to throttle something. The Doctor let out a series of coughs, eventually spitting out a mouthful of blood. He leaned his back against the stone wall and slid down to a sitting position.

Donna reached her hand through the bars and felt around for the lock keeping them contained. She quickly found it, and was suprized to find that it was a normal metal padlock. If she had a lockpick, or even a bobbypin, she would've been able to pick the lock and get them out. She patted down her pockets for a pin, but couldn't find one. She turned to the Doctor, who was looking on the verge of passing out.

"Doctor! Do you have you screwdriver thingy?" The Doctor blearily opened his eyes. He nodded slowly, and pulled himself up. Donna walked over and helped him steady himself, his body still burning hot with a fever. She walked him over the lock and he pulled out the sonic screwdriver. He reached through the bars and began unlocking the cage. He looked at Donna, a pained expression on his face.

"When I say run, Donna, run,"

Donna nodded. A few seconds later, the lock dropped to the ground and the Doctor shoved open the door. The guards turned around.

"RUN!"

They took off through the small village, Donna in front as she held the Doctor's hand behind her, dragging him along. The warriors followed them, spears and arrows flying through the air after the escapees. They ran past the wooden gates of the village borders and into the thick jungle. Donna was running blindly, only following her instincts to the familiarity of the TARDIS. She heard a whistle and a thwak as an arrow planted itself into a tree next dangerously close to where she had been seconds before. She increased her speed, and soon flew into the clearing where the TARDIS stood. Her heart lept with joy at the sight of it waiting for them, however, the joy was soon cut short as the Doctor let loose a pain filled scream. They fell into the TARDIS, and it, sensing the urgency of the situation, slammed the doors shut and took off on it's own into the vortex.

Donna turned to the Doctor and nearly screamed. He was lying on his stoumach with an arrow protruding out of his back. Blood was draining from the wound and the Doctor shook with sobs of pain. Donna lept over to him and quickly pulled the arrow from his back. She turned him over on his back, and jumped back when he seemed to explode with golden light. She put a hand up to her eyes to shield them from the intense light and heat and pure energy that he was putting off.

She slowly lowered her hand when the light disappated, and gasped at the Doctor's unconsious form on the floor of the TARDIS. She stepped back a few paces, shaking her head.

Had the regeneration gone wrong?
