The number of players on Geas waxes and wanes depending on the time of year. Right now is a lull, but it will pick back up eventually. The market centers of Elvandar and Arborea are good places to run into folks. (By the NPC's Beladan in Elvandar and Volog in Arborea.) There is a good number of players for various IC reasons who cannot linger about in Elvandar and Arborean lands without getting hunted down and killed. These folks, if you run into them, may or may not choose to stick around and RP, but please don't be sore if they don't. Also, Skyrim just came out a few days ago; so for a while, several players, myself included, won't be on much if at all.
You can play a peaceful character, and in fact there is an entire guild in the game centered around pacifism. (It may be impossible to join it right now though.) As for Gwen, her shrine is in the wilderness and she has no presence, to speak of, in the cities. (An alternate character of mine is one of the few Gwennites regularly around these days.)
It can be boring during the lulls; however, they don't last forever, and despite the odd issue here and there, the overall game is quite good. So I'm sure we all hope you don't get too discouraged if you don't run into too many of us at this time, and I'm certain we'll all look forward to meeting you IG.
You hear a voice speaking in your mind, telling you "So-and-so is a traitor and
an enemy of the Crusade. The punishment for this crime is death. Go and
execute our will!"
