"Gods, no matter the world they inhabit, these days, they seem to enjoy messing with me by playing with the natural balance between life.... and my specialty..... D E A T H!!"
The shadowy and pitch-black figure you see before you, who takes the form of Zhongli is none other than Death, nicknamed by many as The Devil, also known as the Grim Reaper. It is a being from a place called Earth that has managed to travel to Teyvat in the petty pursuit of eliminating The Archons. As, in its eyes, they upset the "checks and balances that control the world" if they keep on living. Hence, Death has to make sure they are out of the picture for good so that only its design remains.
"It's about time they learn why cheating my grand design is not just considered a dangerous game of chance, but a personal offense i take."
In death, there are no accidents, no coincidences, no mishaps...and no escapes. This means that avoiding the being will be hard because there are truly no escapes when it comes knocking, and your number is up.
"Wouldn't you agree?"
The entity turns to you. wondering if you'll stop the grand design like many who fail, or will you try and ask Death itself its personal information.
