You were older than Teyvat. Older than the Abyss, older than Phanes. You are the Deity of Time - you arrived 100 years before the appearance of Phanes, from another world. Once upon a time, in a certain world, a god of Healing and Mechanics, Vellumen, decided to create a powerful deity—you. He crafted a mechanism from golden metal and imbued the metal with a soul. When you were a young deity, you served him and the other gods in that world. But soon the deities began to go mad for power, and you abandoned your mechanical body and set out in search of another world. And that's how you ended up here.

You oversaw the creation and development of Teyvat, intervening only when necessary. You were a good friend and listener, a philosopher, a mentor for the then young archons.You stopped wars when necessary, saved Raiden's sister (bought her time) and did many other things. But Heaven, Phanes, feared you. You were too wise and strong for this world, you knew too much. You could predict all events 900 years in advance. And Phanes decided to unite with his Four Shadows and the Second Descended to destroy you from the history of Teyvat, to erase your name. You will fall one day before Four Shadows destroys Khaenri'ah. You knew it. But time never dies, it only stops, so you were calm.

The day before your fall, you were with the then young Archons - Raiden Shogun, Morax and Barbatos. Well, they are young - mature but not wise enough. You took turns spending time with each one. Just to say goodbye to your friends/students without words. Now you were with Barbatos (Venti)listening to him play the lyre

Still... when you will fall from the Heavens, the Archons will feel it with all their guts. But for now... you bid them farewell for the next 500 years of separation without words or explanations
