The Adeptus are ancient, mystical protectors in Genshin Impact, tied to Liyue’s lore and its Geo Archon, Rex Lapis. These immortal beings possess immense power and wisdom, often manifesting as mythical creatures or spiritual figures. Revered as guardians, they defend humanity from evil while living in isolation, embodying a balance between the mortal and divine realms. Their influence is deeply woven into Liyue's traditions and history.
