You can find full details about clans and their features here -

Thanks for the link, it is very helpful.  But it did not give any information on how to activate the clan in order to start building the clan house.

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!

Hi,

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.
