Hello is not spent, so ... Hello everyone ^^

To join a clan in another kingdom you need to move to that kingdom using the drakkar which you must buy from the bank

Pour rejoindre un clan dans un autre royaume, vous devez vous déplacer dans ce royaume à l'aide du drakkar que vous devez acheter à la banque.

 (translated by Google)

And then I belong to the new kingdom? 

Can I do this as often as I want?

Yes, you belong to the new kingdom.

You can only use the drakkar item every 30 days. You cannot move to a kingdom less than 2 months old. There are a few kingdoms that are full and you cannot move there.

Ok thank you so much for your answers!

Yes, you should not go to another kingdom hoping that a powerful clan will accept you. You should talk to them first before moving.

Yes I intend to conduct my little study before, and initially contact some clans before moving.

When I am on a foreign kingdom, is there any way to see the list of clans of this kingdom?

If you are physically in your own / or another kingdom, you see the list of clans in that kingdom.

I do not know otherwise.

I have not found a way to see the list of clans in a kingdom apart from my home kingdom or one that I am visiting for an event.

In the Kingdoms map, you could look at who the king is and the name of their clan. Otherwise you would need to go to each kingdom and look around the forest as the strongest clans are usually there.

You could also look at the Events and look for french names in the rankings.

I know there is a strong french clan in 124 - stronghold coords 217 504 but I know nothing more about it.

Yes we can view that list of our own kingdom. 

Thanks Unexpect I'm going to go see this ;)

Thank you for your experience;) 

Mystery mystery so ^^
