A Clan can be joined after clearing the quest [Epic] EP.1 Babylon: Visiting the Asientet Legation.

If you wish to join a clan, you can proceed with Instant Join or by sending a join request through the Clan screen.

Clans set to instant join allow you to join immediately without any additional procedure, while clans set to join request require approval from the Clan Leader or a member with join authority.

Clan creation is possible after spending a certain amount of gold.
