The Pretender Sith (Krayt, Jacen, Lumiya) vs. Sith Triumvirate (Nihilus, Sion, Traya)
The head of the New Not-Actually Sith Order teams up with his fellow not-really Sith from the Past in Lumiya and Jacen to take on the Lord of Hunger, Lord of Pain and Lord of Betrayal (though shouldn't it be Lady of Betrayal?).
The battle takes place on Korriban in the tomb of Marka Ragnos.
All-out fight who wins?
