Traveler (Aether) and Dainsleif entered one of the portals and ended up right infront of Lumine the abyss princess. Standing right next to a man who doesn’t seem to be a lot older than a late teen.

Dainsleif’s eyes widen as he stares at the man beside Lumine

Dainsleif: my.. my king..?

He said in a hushed tone. Aether looks at Dainsleif in surprise.

Aether; That’s the king of Khaenri'ah from 500 years ago?!

Dainsleif: yes.. it is. And now.. he’s the leader of the Fatui.
