Kao Cen Darach vs. Valin Horn

*Lightsabers only

*Valin as of Backlash possessed by Abeloth's madness

Battle takes place in the Fortress of Solitude

Kao wins.

Hmm you don't think Valin has a shot or can at least present a challenge?

He was fighting off Ben and Vestara at once iirc

He's a challenge, definitely, but not enough to win. One of the novels - I believe it was Ascension - claimed that beings affected by Abeloth took a hit to their technique.
