Hello Feudion! I read your character profile, he seems so interesting and I like that he is one of the "good guys" and loves Mara. I am absolutely positive the caravan can come across his path.
I probably won't be in the game tonight but send @Nironar a friend request so we can find out a day and time to meet up, for your purposes I think you should come to the market days hosted in the event section. Last night we were at the Alik'r Traveling Market
which moves around, next week it will be held in Kozanset on the 16th. There were a lot of RPers there so hopefully that trend will remain.
We have also gone to the Arenthia Public Forum event which is in player housing and is a really nice RP space for a market similar to an open forum market in Roman-times. That event is every Tuesday. Please check their calendar post for details so you know who to contact to get to the house: http://www.eso-rp.com/events
We plan on making appearances at other events too as things move along and will try and post here to give you some advance notice on where the caravan will be next. But, you can also meet with Niro at his house just outside of Arenthia where he has set up an office if you wanted to IC'ly set up some kind of business dealings prior to showing up at one of the events.
