Transferring between Continents with Trial version?

Hey, I was just wondering if this would be possible:

My friend has Nightfall.
He wants an Assassin Character to play with, so he gets a trial of Factions.
If he could reach Kaineng Center during the trial period, is it possible that he could do the quest "Sunspears in Cantha"?

I don't know if there is a level requirement on that quest, is there?

It's not possible. His assassin would be locked and he wouldn't be able to play with it.

Ok, that's what I thought would happen. Thanks for your time!
