Ulic Qel Droma vs. Jacen Solo (Betrayal)

Battle takes place in the Valley of the Jedi

Jacen takes this. He's beyond Obi-Wan level duelists at this stage.

Jacen

NJO Jacen is above Ulic, tbh.

Isn't Betrayal the first novel in the LOTF series?

So he's basically Caedus, in which case, this is pretty obvious who wins.
