If anyone is intrsted in a Limbus/sky linkshell check out http://sorcery.forumotion.net/ and post an application or send a tell to Gardy, Rydiablossom or Paud.
I used to run Bust but things got out of control and had to break the linkshell, so now i have loads of time on my hands to focus more on these kind of events. Limbus and Sky will start as soon as enough people show intrest, items will be based on attendance so sign up early to be at the top!
