Tyrian Characters in Cantha

Does anyone know the quest that allows a Tyrian Character to do the Cantha Missions? I have done all of the quests in the surrounding areas in Cantha and cannot find it. I have seen several people from Tyria doing missions and I just want to figure out how to allow my other characters to do missions also. Thanks.

Not sure exactly what you mean, but after the Vizunah mission, talk to the NPC in Dragons Throat and he gives you a primary quest.

How do I get to Vizunah? All of the gates are closed...

I hope I'm not reading you wrong.

The way to bring your Tyrian characters over to Cantha lies with Sergio in Lion's Arch. I had a bit of trouble with figuring that out myself as it was not immediately apparent how to do it.

This is assuming you've merged your account.

You have to do the primary quest to get into Vizunah Square. Just keep following primary quests and missions and they will take you through the story.
