The old clan rank system will still exist but will be known as military rank and will have no bearing on a player's privileges. In addition, the founder and leader of the clan are no longer tied together, so the clan's creator can easily transfer leadership to another member.
Aventurine also wants to "give clans a greater sense of ownership over the world," so the studio is implementing a system that will "link villages to nearby clan holdings." By improving the rewards for village ownership, the team hopes that clans will consolidate their power thus creating more border conflicts as clans attempt to extend their reach. Aventurine realizes that villages "have always been hot-spots for PvP activities," however, so a resource-stealing mechanic is also being added. This will allow any player to steal resource rewards from a clan-controlled village, which means that clans will have to keep close watch over their domain to ensure that they receive all of their rightfully earned resources.
