Summary
“You’re a friend of god and Abyss alike, dear Traveler.” Kaeya had smirked, his judgmental eye raking the lanky figure up and down, lingering on the Hydro Vision and Electro Delusion. “I look forward to seeing what you can do, Childe. Hopefully a few Rift Hounds won’t prove to be too much trouble for you.”
The Harbinger’s eyes had searched just as hard, lingering on the stars littered about the Cryo allogene’s legs and chest. Staring at the swell of biceps that tugged at Kaeya’s sleeve as he crossed his arms.
“I’m sure I can manage, comrade.” Straight, pearly teeth flashed at him, like a beast craving blood behind a man’s smiling lips.
