Luke Skywalker & Mara Jade vs. Eragon & Arya
All combatants are at their peaks, Eragon's and Arya's swords are both able to block lightsabers, but the Riders do not get aid from Saphira or Firnen in any form other than energy for magic, however they do get the Eldunari.
In a single, all-out fight to the death, which side wins and why?
