"I understand how I got here. What I don't understand is why you never brought an end to the Spawn of the Eternal Warlock of War by yourself instead of creating a whole entire realm, just for something you could have easily ended yourself?" Ryuk asked.
"I can't kill him, as I've been cursed by the true Eternal Warlock of War. This realm is a domain of mine that was once locked under a seal, and the Warlock of War placed his spawn here—like his stamp—to ensure I could never recall my domain. I was trapped here in another pocket of the world."
"I needed someone to defeat the spawn, hence removing the stamp placed by the Warlock of War."
"So now, you're free," Ryuk completed as she nodded her head.
"Yes, I am, thanks to your skill that erased the Warlock of War's existence out of my domain," she said.
Ryuk furrowed his eyebrows, but his attention was soon diverted to his body. Right now, he looked almost like a holograph.
