Understanding the Universe.

A/N: This is basically a story that just lists and describes various planets I've invented for the benefit of the Doctor Who fandom. Use them as you will in your stories; all I ask for, however, is that you message me somehow and tell me which planet you're planning to use for which story, and acknowledge me in an author's note.

To describe the planet, I'll tell it like a story/one shot, and use the tenth Doctor plus various companions. So actually, you could also think this as a compilation of mini-stories, to those who don't want to write.

Hopefully, I'll help a lot of you out there by giving you some inspiration!

Disclaimer: I own the planets (in a sense) but I don't own Doctor Who at all. If only.

~Star of Endless Tears~

"The rain never ceases, you know," commented the Doctor with an off-hand tone, his eyes staring out through the window, the view hampered by the sheets of gray water pummeling down from the Heavens. His hands were shoved deep in his pockets, his frame unusually still from a serious air that had been surrounding him as soon as he stepped out of the TARDIS.

"Seriously, never?" Martha asked disbelievingly, her eyes squinting as she tried to see past the rain. She was dripping, soaked from the roots of her hair to the toes of her feet; the Doctor had inconveniently parked the TARDIS on the outdoor landing pad—which, although free parking spaces were easy to find, left the inhabitants of the vehicle drenched the second they braved the forces of nature outside.

And the forces of nature where certainly an impressive sight indeed. There was no land what-so-ever on this planet, a sphere entirely covered in gray churning waves of dangerous looking water, the kind of dark water that you could almost see people drowning in. The small room they were staying in was part of an emergency landing pad for ships that need to refuel or restock—though it took a desperate star ship to brave the angry thunderous storm clouds and skill to find and land safely on the few well maintained landing pads.

The TARDIS didn't have to face this trouble, simply materializing on the spot, but Martha wished they had just appeared inside instead of outside in the cold rain. Then again, she mused, she should be happy they landed somewhere moderately safe in the first place. Usually the Doctor's uncanny sense of direction landed them somewhere dangerous almost immediately. So far, there was peace; if you could count raging storms and near total isolation "safe".

Nodding, the Doctor shrugged and said, "Yep. Never ever stops raining. It's been like that for tens of thousands of years. Sometimes it lessens up a bit, but it never stops entirely." Waving his hand vaguely at the glass window, he said, "Believe it or not, but the locals would consider this a very good day in terms of weather." As if to re-enforce his point, a loud clap of thunder shook the very foundations of the concrete hanger they were taking shelter in.

Cocking an eyebrow at the Doctor, who was once again staring out into the night with dark eyes, Martha turned and gazed once more into the rain, where she could just make out faint lines of light; thunder and lightning crashing throughout the stormy skies.

"I haven't seen any locals yet, but I bet they're fitted out with gills and scales and possibly a cold-blooded nature; because I can't see anyone liking this place any other way," complained Martha as a shiver racked up her spine, her arms rubbing up and down her leather jacket in a poor effort to warm her up.

As if he only just noticed her predicament, the Doctor jumped slightly and hurried to remove his long, brown trench coat, draping it lightly over her shoulders, the hem brushing the floor because of her shorter frame.

"Most of the natives living above the water are most definitely humanoid without gills or scales, but you're right in that they're cold blooded," informed the Doctor as he adjusted the jacket to cover Martha in the most efficient way. "Only difference is their snouts. But if you see them, try not to openly stare at them; it's considered rude."

"Thanks for the warning."

Lightly damp, the trench coat still brought with it a degree of warmth, a feeling of security and comfort, possibly just from the familiar smell of the Doctor clinging to the material. Martha smiled up in gratitude, hands holding the front closed, her eyes crinkling at the corners, lips tugging up to show a flash of white teeth.

But when he saw her eyes, sparkling and warm, the darkest shade of brown imaginable; he had to look away. The look was too familiar, too much like the way Rose used to look at him, when they shared the TARDIS together. Suddenly uncomfortable, his eyes darted to the right, back into staring mindlessly into the glass, ignoring how he could only now feel the water seeping through his clothes and into his skin.

To fill the growing silence, the Doctor began to babble nonsensical, unimportant facts about the planet, telling Martha things that he knew to be interesting. "Although listed to be officially called the Dronomea planet, a rather dull name in my opinion, most people—local Dronos especially—refer to it as the Star of Endless Tears."

As if scripted on queue, Martha asked, "Why's that?"

Taking a breath through his nose, the Doctor continued, "Well, these people believe devoutly in the existence of a goddess who controls the seas and of a god that controls the air—"

"Sort of like Poseidon and Zeus, right?" interrupted Martha.

"Yeah," agreed the Doctor. "'Cept that the Poseidon was a girl in this story. So anyway, there's a sea goddess and a sky god, who got along fine and dandy. No rain, no storms, just peace. Records show that the planet was once like this, but it was eons back. I'll take you there later if you'd like to see the difference," offered the Doctor.

"Sure," laughed Martha, still enthused about time travel. "But first get on with the story."

"Right. One day, the legends say that the sky god fell in love with the sea goddess, but she refused him because she was in love with the moon god," the Doctor paused sneak in a cheeky wink at Martha, "and that started a war, because the sky god, who couldn't take a dumping with grace, started up terrible storms so that the sea goddess would never be able to see the moon god; which just peeved her off a great deal. Thus the unsteady churning seas. Also, it is said that the ongoing war has sapped this planet of colour, which is why everything is in black and white, and a hundred-thousand shades of gray."

"Huh. So the locals believed that jealously ruined their planet?" queried Martha.

Wide eyed, the Doctor exclaimed, "Oh no! Quite the contrary. The inhabitants of this planet all believe that the sky god and the sea goddess should be together, so they're quite mad towards the moon. Who is totally innocent in my opinion." The Doctor straightened up suddenly from his previous posture of a comfortable slouch, but Martha didn't notice the sudden change, her eyes watching the fierce storm with a new insight.

"These people sound like idiots," snorted Martha with a frown, thinking about how ridiculous it was to hate the moon.

"Are you referring to us?" a new dry voice cut through the silence with a hissing snarl, freezing Martha to the spot, not even letting her turn around to see the person who entered the room so stealthily.

The Doctor looked at Martha pointedly and said loudly, "Uh-oh. You're in trouble now."

A/N: There we go; chapter one, planet one. What do you think? Inspired by the rain falling outside my house and partially from Star Wars II. O_O

By the way, I'll take requests for this story; if you have an idea for a planet/setting you specifically want to see come to life, just tell me and I'll work something out.

Reviews would be awesome, especially if they're to tell me that you're going to use the idea!
