When I went into Old Athens for the first time at level 8 or 9 and was freaked out when a Rookie Clan Trader attacked me. I was losing the fight pretty bad until some HUGE level 30ish person killed it with one nuke.
I subsequently ran lost through the city for 20 mins before I got even more lost by running out into the Athens Shire. Thinking about the layout of the place, I still don't know how I got there without running into West Athen.
I ran lost for another 45 minutes and eventually found some big place called The Academy.
I was so frustrated that I couldn't get home that I went out and attacked a red reet so that it would kill me and send me back to my preciously safe backyard.
