Based on all the requests we've seen posted by folks looking for vampire/werewolf bites, we've created individual threads for players on each console server to coordinate these bites. Our hope is that this will make it easier for those interested in acquiring and/or spreading vampirism and lycanthropy to do just that. Please use the thread for your console and server to post what you're looking for or find willing victims.

Additionally, you may want to check the Recruitment section of the forums for your region/console to see if there are any guilds looking for players.

Thanks, everyone!
