Hello!
For an in-game clan, we have an official discord server with a special channel called "clan-recruiting" in which you can ask that you're looking for a clan, if somebody is interested by your request, he should get back to you via private message. You can click here in order to join the server.

If you'd like to go a bit further regarding clans, there are eSports clans too which basically participate in tournaments organized by the eSports team. If you are looking for a clan there too, feel free to take a look at the website by clicking right here.

Hope this helped!
Have a good day!
