Without wanting to complicate matters it was actually a feud between 4 clans not 3. As it ran alongside the Selen incident, which according to the wiki for that was between Talydran and Arcona that leaves CNS, TAR, CP and CSP competing in this one. Seem to recall fictionally we were all having seperate fleet battle simulations or something in the Aranna system and there was a bit of conflict between the fleets.
Not sure what the exact placing was but CNS came first winning a Nebulon B2 Frigate (Which we named the Fire of Sepros).
Hope that helps a bit.
