The new Stoneheart character in Honkai: Star Rail has allegedly been leaked and they will likely be the first of their kind if the rumored information is accurate. The Ten Stonehearts compose a faction of executives within the IPC (Interastral Peace Corporation) and each of them is named after a special stone in HoYoverses turn-based RPG. So far, players have met characters like Topaz, Aventurine, and Jade in Honkai: Star Rail, three important Stoneheart characters, but there are still eight more units to meet. This includes the groups leader, Diamond. The developer has already teased all of them.
