Heya!
Welcome to Balmung!
Assuming you are referring to the Quicksand, most people are just in there watching but are very willing to RP if you start a conversation. I'm very new to it myself so if I catch someone glance my way I will usually do an emote and sometimes something initiates, sometimes not.
It's not much but it's all I got. I'm always interested in meeting people as well so feel free to look me up. PM or in-game.
Take care!
