Factions character in Proficies?

Just a quick question, how do I get my factions character over to the proficies campagne?

I am level 11 and can get to the market place and KC but havent been able to find out how to cross over yet? Do you have to get so far in the main quests before it opens up?

Thanks

He will give you a quest, Chaos in Kryta.
