Vizunah Square mission... How do I start it?

Before anyone will tell me I have to do the marketplace quest, that is already done

But I am really lost now and have been fizzling for about on hour now. Just so you know, I am only playing GW for like a week or so, so I am the worst noob ever. Still, this is really my last resort!

My problem is: I saw the mission movie, and when I talk to Guardian Pei, He explains me what I need to do on the mission (Togo etc must not die, blabla) . The quest itself isn't in my questlist, and I have no idea where to start the mission, since only the zaishen agent has a ! above his head, So I am lost on where to go, since I can't find myself the way.

Please help this GW noob where I can start it xD I can't go any further in Cantha without the mission.

Thanks in advance.

You just press the "Enter Mission" button in the party list.

LOL I was so busy looking for an npc I didn't notice that button /faceslap

Thanks so much <3 xD I feel so noob haha!

Just for your future reference, Prophecies and Factions missions are begun with the "Enter Mission" button, whereas Nightfall and Eye of the North missions are begun by talking to NPCs.

Yes and no if i recall right.
There is 2 types in gw - quest and mission.
Quests you tend to get from npcs but missions require the enter mission button and often you will find after a quest you arrive in an outpost and if theres no quest npcs then its usually a mission.
And in nightfall as far as i recall all the missions have the button and are not started by npc ( consulate docks comes to mind ) tho a few maybe npc.Missions act towards protector title and eotn doesnt have a title for missions and hence there is no mission buttons

@op - its an easy mistake and one that almost everyone has had in their time in gw - its more common than you think.

Thank you so much! I played Nightfall a bit before Factions (bought the triology) Maybe that's why I got confused, Thanks for clearing it up!^^
