Hi, 
This thread could be helpful for you.

I don’t play Larkinor myself, so I’m not sure. It does explain what needs to be done to build the clan house.

Maybe it’s a start - take a look and see what you think.

There is a moderator here named 'ezekial', she’s a Larkinor player and would likely know the answer, but she’s been inactive for some time.

I know that’s not much help, but you could try searching through her forum posts or browsing the Larkinor section of the forum to find more information.

Sorry I couldn’t be of more help!
