Piltover is ruled by various merchant clans through its councilors. This entity consists of representatives from Arvino, Cadwalder, Ferros, Giopara, Holloran, Kiramman, Medarda, Tariost, Morichi, and Torek clans. There are also a few other clans that participate in sharing the power, but they weren’t named in the official League of Legends lore or Arcane series.
