Hello Asura, I'm a returning player since May of last year (after quitting back in 2008), and I've been spending a lot of time re-exploring the game from the start on a new character with a few close friends.
I can't say I'm too familiar with Escha as a whole- I've only really been to those areas for RoV missions, and Escha-Ru'Aun to farm a Refoccilation Stone. But I'm interested in buying a Lathi if anyone/group out there is willing to help. If so, please just send me a /tell in game with your price. I don't have a set playing time, but I'm usually on everyday at some point.
