Welcome to Gaia! ::

"Hey KiraX, come here!"
...
"Are you even listening...?"
...
"Allright."
Then I- Oh, yea, introductions. I'm Checkered Grey. Let's see... I spend all my time around KiraX, our towns resential money man. He pays no attention to the fact that he's rich, but his specialty is being rich. His cutie mark, a dollar sign, proves it. Money comes naturally to him. Then there's me.
I was born with my cutie mark. It's very simple (a 2 by 2 segment of a checkers board). What does it mean? I don't know. All I know is I'm ponyville's resident genius (other than that Twilight)... Oh, I'm off topic! Back to the story.
"Allright."
Then I went over to KiraX and gave a sharp kick to the back, sending him a good 2 feet off of the bench. "Who-what-when-why-how-COUGH"
"Stop sleeping on the bench, we have to get to work" -silence-...
...
"Bah hah ha ha!" (both of us)
"C'mon Checks, we know we don't have to work! I got us covered!" As the richy boy pulls a wad from his pocket. "I know Kira, but I don't want people to think we're lazier than we already are." "I know, I know, I was toying with you. Let's check the odd-job board today."

-Escaped lab mice-
Some of my lab mice escaped, can you help me gather them?

I found a new way to dye anyponies coat and I need a test. Don't worry, it can be undone with... Reletively no marks :3
~Twilight Sparkle

*Me and Kirax stare at eachother*

And KiraX says "I guess we're getting lab mice for Twi again, aren't we?" "No wait Kira, look at the second one..." "So? Our cutie marks are nor-... Fine. We'll take it."

I woke up in my hammock. I have a house, but it's more of a shed. I never really used it other to store some cloths and food. It's a cold-ish Autumn morning, so I went inside to grab a hand-made sweater. The design's purely mine, along with everything else in here, but that one girl at made it for me. I'm not to fond of the fasionista type, and she kept trying to embroil my jacket, so I never bothered to learn her name.
I went over to KiraX, who also slept in a mini-house. He might have insane amounts of money, but he never uses it. He flaunts it all the time, but he says he's saving the money for 'it'. Anyways, again I bucked the living buck out of him to wake him up.
"Ow! Dude, just wake me up like normal, please! Just once!"
"I did -glare-, stop accusing me!"
"-glare-"
"-glare-"
"Fine. Twi said-"
"Twilight."
"You call her Twi. Why can't I?"
"You're not a good enough friend."
"Fine. Twilight said we need to try to find out your cutie mark's meaning. Wanna play checkers?"
"You know just as well as I do that I suck at checkers. And chess."
"Where do we start then?"
"Where can 'I' start you mean, I need to do something alone."
"Fine, just don't get me arrested again."
I walked off twards the library. It's a public building, but no one considers it one still. As one of the two people that actually read, I still just walk in. Twi hates it when I do that, but technically she told me to learn, so I am.
I walked in carefully and slowly in an attempt to find anything checkered related. Sadly, I knocked over a book tower Twi had set up. Each book was about special cases of cutie marks. Twi didn't budge, but Spike was awake, still in his half-groggy status.
"Sup Spike?"
"Be quiet please, I'm trying to sleep"
"Sorry' I'll try."
Spike waddled back up stairs, every now and then hovering a bit. He's still a baby dragon, but he's learning to use those little wings. Anyways, I went searching for books related to checkered marks. Nothing other than a how-to guide to chess. Figures. On my way out, my mark started glowing so brightly I had to squint to see. Twi was down in a matter of seconds, screaming loudly, but I couldn't hear her. Everything but her and I were smashed into the walls and bookcases, when the bright light turned into perfect darkness. We were both fully conscious as Twi began to light the place up with her magic. We were in a endless room with a checked floor.
"Where are we?" I tried to keep my complexion, which was easy. As the room got dark again, I could tell Twi wasn't able to keep hers.
"Where are we?! How did you do that, you're not even a unicorn!" She was hyperventilating. I went over next to her to calm her down.
"Something touched me!" She blasted pure magic bolts into it, I mean me, sending me flying about a good 8 feet.
"Ow much. It was me." As I got up, I asked her to make a magic torch or something to keep the room lit. She made a magic fireplace. Good enough.
Twi went from histaric strait into examination mode. She found out that: A)this room went on forever, so there was no hurry to escape, B)we were alone, C)my cutie mark was gone.

*Summery*
Me and Twi were sent somewhere.
My cutie mark caused it and disappeared.
