You choose a name for a new page you want to create (e.g. "onihk's great page of greatness"). You enter in the box on the sidebar and click "New Page." You go to a new page with that name and edit it. It's that simple!
As for the article itself, I'm not really sure what's going on. Part of this is the fact that there are a lot of run-on sentences and paragraphs that really should be four or five separate paragraphs. There are also a lot of places that are missing punctuation, making it more difficult to read.
Aside from technical issues, the reader has no real context for what's happening. I think there are some very lovely descriptions and images that you manage to convey, but there's not really any reason for them to stick in the reader's mind. I think that there's a lot you could do with this, but it's still in a very unfinished state.
I'm curious what you were going for with this piece. Maybe if you can articulate it, we can help suggest ways to make it clearer.
