I'm writing a fantasy series too. I'm only about 11,000+ words into book 1, but I have my storyline completely written out. I've also created a lot of reference material for myself so I can keep my storyline more consistent. This includes character bios and portraits, an illustrated map (including an interactive version for my PC that I created to make for quick reference of city names, agricultural details, government information, terrain and any other pertinent information about that region), an extended history of my world throughout its ages, an illustrated flora and fauna guide etc. I'm not rushing on these books. I want to be happy with the first one before I try to find an agent to represent me. I expect that this means I won't be looking to get published for at least 5-6 years, and since I've been working on this since 2003, that puts me right at about the 10-year mark. That's how long it took JK Rowling to write her first Potter book.
