If you are talking about the first quest, go to the crystal, and it will teleport you to the guild.
there she will explain, blah blah... and ur done with that, then u can do what i posted on my previous post, if you want to, thats one way to do it
or you can wait to get more people that will join you... but obviously it will be easier if u get 5-6 ppl right from the start
