I might be interested, depending on the following:

1. When you say fantasy, do you mean magic? If so, what kind of magic? If not, what do you consider fantasy and how will it involve the two main characters?

2. What age do you have in mind for our roles? Teens? Young adults?

3. You say you want a paragraph or two per post but I personally feel comfortable giving three or four. Is that okay with your or are you trying to stick around the Casual level?
