The “Masters of Ashan” clan.

People, I know a Centaur, and he advised me to seek help from a clan. I'm creating a campaign based on an Elven manuscript (a metal opera by the Epidemia band), but I'm having trouble with the scripts. I can't even display a message! And I want to make the plot rich and close to the manuscript.
What do I need to do to join a clan? =)
