Hi, I'm new to this server (like, a few days new)... and learned very quickly that we can attack anyone and be attacked at anytime. Is this some kind of unwritten rule on FRO? Just attack whoever you feel like because you're feeling 'random' that one day (true story)? I noticed I haven't been attacked by other players in towns, but it's happened several times in dungeons where I'm minding my own business and trying to get my quest items and then suddenly, someone teleports in, sees me, and think it's funny to kill me and then run off (or teleport somewhere). So what I'd really like to know is, what are the fine lines on killing whoever you please on this server so I don't go and make noob mistakes?
(I hope this isn't a repeat topic. I tried doing a search and nothing came up so I hope this the right place to ask this.)
