Chapter 1: The pony from the sky

It was a stormy night in pony vile as twilight sparkle and spike were working hard, much to spikes discouragement. "Twilight, its twelve o'clock midnight. In case you haven't noticed we and owlisios are the only living beings in Ponyvile that are awake."
Twilight turned to her assistant with a glare and said "spike you know that we can't stop now. You know that the current weather patterns are causing catastrophe throughout all of Equestria. Even this storm was something that the Pegasus ponies were hoping to try to stop. Rainbow is freaking out about the fact that she can't stop it." (Thunder clashed) "And it's not just that" continued the purple unicorn pony, "the animals have been seeming to riel up at something like they can sense something dangerous is happening. And it's not just happening here, according to princess Celestial, all of Equestria seems to be spiraling into a state of total natural chaos."
"OK" responded the dragon "but do you really need to be studying that slab of rock." He points to the rock those days earlier twilight found. IT was a strange rock indeed. The pattern on it was like nothing either student or assistant had ever seen. "Spike I know you don't believe me, why I don't believe me when I say this, but I feel like this rock may be connected to the answer of our problems. Not only that but it feels almost like when I walk by it, the rock seems to call out to me." Twilight responded. Spike stared at her and responded "So is my BED! But you won't let me investigate that." Twilight looked at the clock saw the time and finally she gave up saying "all right I guess it is time for us to get some shut eye." Then her ears perked up. "Spike, Do you hear that" Thunder crashed. "You mean the thunder, kinda hard to miss!" "I think there is someone outside." She went out in the rain and she saw what she could only describe as a figure falling from the sky, she looked closer as lightning struck she realized that's exactly what it was. She ran out to the landing spot not less than an equestrian block away and she saw an earth pony laying there nearly motionless. Its hair was black and surprisingly it had no cutie-mark. She checked the pony's vital signs and breathed a sigh of relief that the pony was somehow ok. "Spike, help me get this pony inside." She called to her assistant. He rushed out awestruck. "Shouldn't we take him to the hospital" he said to her. "There's no time the pony might die if we take him there." She saw his muzzle and realized seconds earlier that the pony was in fact male. "Who is this pony?" she asked herself. Little did she know she had just helped an ally in what could only be the most important adventure of their lives.
