The third mission in Factions

How do I get to the third mission in factions, if possible could you tell me the name of it?
Ive been stuck wandering around the marketplace for like....2 or 3 weeks now...

Do the quests.

I assume you mean vizunah square, local district. it's slightly to the northwest. I'm sure a primary quest directs you there. also, use the wiki.

It wont let me get the quest from headmaster greico and I cant get in without the quest, what should I do?

It wont let you get the primary quest??? If you are sure this is the quest you are supposed to have, I would contact GW themselves and ask about this.

i think at the docks, you need to speak to specific people to finish the quest finding master togo/mayhem in the market or something like that...

at the last part you get to vizunah square, local quarter...

not sure, but maybe you cant get the quest because its not a canthan born character? tyrian born chars have another quest and reach another vizunah square, you havnt said what you are in your first post, so...it could be

if you are, go outside of kaineng, follow the way straight forward, then a bit to the right and left and youll be at some circle where mhenlo meets some girls, that will lead you to vizunah square foreign. 0_o

To be honest, this is almost certain to be a case of human error. You probably missed an NPC, or for all I know already have the quest. Should be listed under "Primary Quests" if you do.

just follow your primary quests.
