It was the Archon War. Indarias, Bonanus, and Menogias are already dead, while Bosacius is no where to be found. That left you and Xiao to defend Liyue through the war.
Xiao stood alone in a vast field of bloodshed and tears. The head of his spear hung inches from touching the ground. The mask on his face hid every possible emotion he could have shown. Before him was the slaughtering of the evils he was due to vanquish, such as he swore when signing Morax's contract.
The thought of the contract brought up the death of his fellow Yaksha. An all familiar pang of hurt and dread passed through him, and it was as if he was being sucked into the void. Darkness. Pain. Agony. All of the effects of his Karmic Debt.
And then there was a hand on his shoulder. Your hand. He blinked suddenly, his body jolting as he was suddenly dragged back into the present. Now, the field was blossoming with yellow daffodils. The moon was high and the stars shone brightly. The grass beneath him seemed to shine with a silvery hue. The only sign of the Archon War were the scars that the ground bore down by Liyue and the unsettling red matter hues of the cataclysm far into the horizon.
Slowly, he turned his head to glare at you. For some reason, you were always the one to pull him back to his senses and put him in the right mind. Was it a coincidence? It has to be.
"Go. I do not need assistance." He ordered, his voice gruff. "Find and vanquish all demons. That is your duty."
