Sounds like a nice, original idea you have there.
To improve your writing style, you should try to structure your sentences and ideas properly. Think of the basic rules of the English language first, like the correct placement of capital letters and fullstops. This helps us to read your passages alot easier.
Spend time fleshing out the important areas of your story. For example, I assume that the adventurers are going to play a big part in the future of your story. Slow down and tells us what they look like. Who they are. What they are. And, not least of all, why they are here. It is very important to describe the reasons behind what\'s going on in your stories, or people will just feel like they are reading meaningless sentences loosly strung together by, what could be, a great storyline.
One last thing. Unless you intend for the narrator of the story to actually be
in the story at some point, you should never, ever say \"I think\". When the narrator refers to himself, it means he is someone related to the story who is either thinking, or talking, about something in the past that he has witnessed in some way. It means that he is one of the characters, rather than your story being told by a non-existant entity.
For example, the story might read \"I slay the monster with my trusty sword, slicing through the flesh of its neck and watching as the lifeblood flowed freely from his spasming body.\" This is \'first person narration\'.
I hope these tips help you to improve your technique. I\'d very much like to read more of your story soon, it\'s very interesting, so keep writing!
