I'm also working on a KOTOR fanfic, a K3 one to be more precise. It's also probably gonna be my first SW fanfic, but I'm only in the planning process currently, because school is eating much of my time. I'll probably start work on the fic in the summer, but until then I'm still gonna be thinking of the plot.
Anyway, the fic involves both Revan & the Exile's return to Republic space, but it also involves the story of a new character, Arrik Degan(a name with which JC's familiar
). But on to more details...the main idea is that the Exile turns evil and she leads the hordes of True Sith warriors(who's nature I won't reveal yet) against the Republic. Thus a great war takes place, and the Republic will have both Revan & Rik Degan on their side, plus Canderous' Mandos. But they might not be enough to stop the True Sith threat...
Moving on, I'm also planning on making a sort of cover which will act as a teaser for my fic, until I actually start working on it. The cover will probably feature the three main protagonists: Rik, the Exile & Revan. Not sure when I'm gonna start work on this one either, as I want to make it look very good and I'm still not very good with Photoshop. I'm also planning on using 3DSM to help me out with the makings of it.
