The deceased ancient Aeon who presided over the Path of Propagation.
As the last member of the Coleoptera, Tayzzyronth's form was a horror of self-replication, a vanguard what opened the floodgates of infinite reproduction upon worlds.
Tayzzyronth — Tayzzyronths rather — fluttered across the universe until THEIR advances were halted by gods.

The Propagation

"With stars above, everywhere doth evil lurks! Under the witness of the solemn skyscraper, recite your final words — *three gunshots* — The winner has been decided. My Cosmic ninjutsu methods are ever-changing. Better luck next time... in your next life."

The Dazzling Ninja

"This coffin isn't mine. I was merely entrusted to take the body back to the Luofu."

Laic Pursuit

"There's always a paradise that needs to be built. That vow is like the sun in the sky — perhaps I'll melt and fall before reaching it... But some hardships I must endure."

 Eyes to the Stars

The nurturer of all beings and the Aeon of paradise. THEIR aim is the continual proliferation of life.
Yaoshi presides over the Path of Abundance and is the sworn enemy of Lan, Aeon of The Hunt.

The Abundance

The Merlin's Claw

The owner of Bubu Pharmacy, the finest pharmacy in all of Liyue. He is rarely seen without a white snake named Changsheng coiled around his shoulders. His prescriptions are varied and diverse, and his medical prowess and compassion are known throughout Teyvat.

Beyond Mortality

"I am a Vidyadhara, born and raised on the Luofu, and I once studied the healing arts under the name of 'Dan Zhu.' But my master became bogged down in politics and was banished to a place far from home. I followed her there. Now that I've changed my name and come home, many complicated feelings have returned."

New Alchemy Commission’s Cauldron Master

"All sorts of business are welcome — as long as you've got the cash."
