Edit improvements to English text

For Issue #420. These edits fix grammatical mistakes, correct capitalization of many words, fix overuse of certain types of punctuation, and generally make the text more consistent and easier to read. Especially for the dialogs that occur between characters in the game. Hope you like these changes. It took me several hours to go through every line of text in the game.
The use of 'further' and 'alone' together here doesn't make sense then. By alone, we mean "without companionship". Generally people say "more alone" when referring to increased degrees of loneliness. I found this line odd since Kayla is with both Bronnan and Orlinn when she says this line. I wonder if instead of alone you meant 'isolated' (from others/civilization). Or you meant to convey that Kayla had never been any further than this before in exploring the mountain. If you can explain what it is you're trying to say here, I can give you a more suitable line that matches what you mean to convey.
