But who could truly face Thrawn? Very few can outwit him.
Pairing him with the Ascendancy would be bad news for anyone. It would be best to use his personal Empire: Empire of the Hand of Thrawn.
Perhaps. But I'm sure theere is SOMEBODY out there who can give him a run for his money. Besides, it'd be a shame to neglect giving a Kaggath to Thrawn because he's awesome. That's flawed reasoning. He should get a Kaggath because he is awesome!
If there's no one who can match him then could we consider paring up two lesser forces against him? Thrawn will get a Kaggath one way or another.
