The last I've heard of Scania HS, it was lead by a mapler named WonDark, whom I've never heard nor seen on the boards. So... contact him in-game to see if he still leads the guild or not.
As for Broa, I heard that it disbanded, but Wigum or Daos would probably know more about that than me. As far as I know, it hasn't been active in months... possibly over a year now.
