Holy crap. A bloody Ayokyan. How did he forget? The massive cities, the sandy terrain, their lifestyle of digging massive underground caverns. Wait a minute, he wasn't underground? What were they doing above ground? This was not a good sign.
Now, for anyone who has never seen an Ayokyan, you might be a bit confused at the moment. The Doctor met them for the first time right after Rose said no to his request that she join him in his travels. During the time he spent considering whether or not he should go back and ask again, he travelled the universe multiple times. The Ayokyans are an insectoid race, with mantis-like faces, but the body of a centipede, and they are as long as a bus, and as wide as one. They are avoided by the rest of well, everyone. They have an unnatural attraction to blood, as in, well, they're attracted to it. Jack Harness once told a story of a time that he crash-landed in one of their colonies, and well, he had a good couple of nights with a few choice Ayokyans, let's put it that way.
Quickly patting himself down, the Doctor was glad to see that he had no cuts that were currently bleeding. His recent regeneration had caused an influx of regeneration energy, meaning that all the cuts he had retained from his crash on Earth had been healed. Wait, crash? That was something he hadn't remembered. A crash, and a promise to an important individual. His situation was looking worse and worse. Realising that the Ayokyan had put her head down, he quickly sunk to his knees, making sure that she didn't attack. Her eyes glinted with approval. "You are worried," she muttered. "There's no need to be. You have proven your respect for my race, and you are not attractive enough for me to want to do anything else to you. You are not… leaking." The Doctor let out a breath he hadn't realised he'd been holding.
Of bloody course it was the Ayokyans. How did he ever forget them? They couldn't breathe in methane or krypton. That was the only reason why they weren't still on Earth. They were the first species to walk on land, but quickly left when the air started to become polluted with the two toxic gases. It's good that they did, because with all the wars that had happened, their hormones would be raging almost constantly, and last time the Doctor checked, most humans disliked interspecies sex. Most of them.
The Ayokyan coiled around the Doctor, gently pushing him onto her back. She was old, he realised as he felt her battle-scarred shell tense beneath him. She started moving toward the centre of the city. Looking around, the Doctor noted that their technology, while relatively primitive, was well-made. He had so many questions. How did they get the materials to this planet? They normally ate insects and small critter that lived underground, so what were they eating? He decided to save his questions until he met the King. "My name is Rakshir." She said. "I am surprised that you do not have any questions for me." It was as if she had read his mind.
"Um. Well. I have a few I guess, but I thought your King would be better equipped to answer them." He replied.
"What makes you think that I am taking you to the King?"
"Well, isn't that what you normally do?"
"Yes, but instead I will take you to the other one of your kind."
"Other one? I'm not sure I understand what you're saying."
"Jenna. She informs us that she is a human. From our elder planet."
The Doctor was perplexed. There was a human here? Was he being taken to a dungeon? Maybe they planned on torturing him. They did like blood, after all. Rakshir just smiled, and laughed to herself. Maybe he should run for it. That might work if not for the fact that the Ayokyans could travel up to 70 kph when running. The doctor felt a knot in his stomach as they reached a dark metal door.
