Return of Reckoning

Is there anything you have to do to start the duel? Talk to an NPC? / command?

I'll check out the war quarters and we should be able to figure it out from there.

Is there a place on Order side?

Is it possible to duel my friend? We're both level 10 and have a tradition when we start new MMO's to duel each other throughout our leveling experience.

Thanks for any answers.
