A creature that has never been seen before comes to Equestria from an island over seas and makes port after dark. Nopony has ever seen a creature like this until three fillies find him in an abandoned mansion.
Nothing is known about this creature, there is nothing about him in any of Princess Twilight's books for information on it. So there is no other choice, they have to get the information from the creature.
I like the story.
I like the premise of the story. Kahmey running from the windigoes and getting found by the CMC is a pretty good way to start the story. Your writing style however needs work:
The paragrapgh this is from is a little large and may benefit from a bit more detail in more paragraphs. For example: Is he the only one left? Was the ship part of the village, and if so, it may be a bad idea to sail the largest ship alone.
Especially for online reading it is best to keep praragraphs small!
More important however: You begin with 'I' four sentences in a row and then begin with 'When' twice. Combined with your repetetive senternce structure (I did this, then this/ I did this, so this happened) the entire story reads more like a list. I recommend playing a bit with different sentences:
This for example gets rid of the 'I' in the beginning and for a change doesn't have Kahmey as the acting part in both sentences.
This is another example How you could shake up your writing style. Notice how instead of main- and subclause it instead is one sentence with additional information?
Now i don't claim these examples are perfect or the way to go for your story, but your writing would really benefit from a bit of variation.
Hope i didn't come off too harsh, if so I'm sorry.
Thanks for the tip, I appreciate any possible help.
