Is it possible to transfer the clan to another owner? Yes!
1) Log into the Bloodlines website 2) Go to your clan management page 3) Fill out the form to transfer the clan to another player
One caveat: the person the clan is being transferred to must be a direct Minion of the current Leader doing the transferring.
Once the transfer goes through, the two players will effectively swap liege-ships. The Minion will have their liege set to 'none', and become the leader of the clan, and the former leader will have their liege set to the former Minion / new Leader.
