the map is called ban island in uk metin,my wifey used to take me there when she didnt want noobs to disturb us in uk,she said its where the gms spend time when they arent helping people,and you cant get there unless a gm teleports you as far as i know unless its changed
yep the red girl is a gm she spawns mobs,i assume she altered their gold drop and the sura guy is probably her friend or something so shes helping him or they are testing something,they used me as a tester in uk for quite a lot of stuff xD
