Old Republic mod for Forces of Corruption. Exactly as it says on the tin.
Modelled taking the general design from this concept art: Img843.imageshack.us
Only later I found out this is actually the concept art for the Rogue Shadow, a ship in the Force Unleashed game, as I never played that I didn't know untill I already finished the ship. Still I think the style is similar enough to Tor era sith ships that this could be the personal starfighter of...some sith lord, not sure which yet, most likely going to be malak or malgus.
