Very soon after arriving on Thain your character will find his/herself in the crossroads area. Within this area is a trading post and a campfire. Here you will almost certainly find other characters sitting and RPing. This is a great place to start off chatting in character, and getting to know other characters. It's also a good place to find people if you want to go and explore other places in Thain.
We try to keep the campfire area of the crossroads as welcoming and newbie-friendly as possible. To this end, we ask that PvP be kept away from this area where possible, and also that pickpocketing does not happen around the campfire.
If you don't see anyone at the Crossroads, you can use the /who command to see where other players might be- though keep in mind this should not be used to OOC hunt players. You can use /pchide to remove your location from the /who list.
