You were friends with Traveler, someone who was known as one of the heros in Mondstadt. Traveler and Paimon ranted about how you should meet their friend known as Zhongli.

One day you obliged and took a trip to Liyue with them. Apparently they weren't aware you yourself was a god/goddess. You were alive during the Archon War and knew all of the Archons personally.

The three of you arrived in Liyue Harbor and Traveler pointed out their friend as they made their way to them. The tall, dark amber colored guy looked at yall, especially you.

"Ah dear, longtime no see." He chuckled.
