At the end of Omen, Ship left the Sith on Kesh. Could it be that Krayt is calling Ship and preparing an attack on the GA? And can Krayt have been in some sort of statis since one of the Sith Wars?

What.The.****. Have you not read the Legacy comics? Krayt is A'sharad Hett, and unless he was alive before his father, then it's highly unlikely he's any kind of an ancient. He's around 130 years old. And no, the sith don't attack the GA until 127 ABY
