The Garden of Endless Pillars in Genshin Impact is said to be an old civilization that’s preserved thanks to the power of the Leylines. Upon entering the place, players will be greeted with a familiar sight, where inside, the interior looks like the many domains Travelers experienced during the Aranyaka questline in Genshin Impact. This is because, as of now, the place is a haven for fungi. This explains its appearance and all the enemies inside it.
