Many officers in both these 2 guilds left the guild as xartanos said, because of some power abuse from GM and some indifferences according to where the guild was going and some certain incidents so after the mass exodus from the officers, many members left too after some days, and created 2 different guilds which were Of Sound and Fury and Angry Birds. that's the story in short terms. these 2 guilds exist in game until now.
