changing leadership

could someone plz, enlight a newb (me) on how to change leadership of the clan plz?
i saw on game tips that it can be done through an npc, but which one?

Try the Head Priest in the temple, where you do all your clan related stuff..

Go to your class headmaster, thats about it, there's an option for it there, the other member you want to switch it to need to be there.
