After leaving Hades, Arthur returned to the place where he'd spent the greater part of the century he'd been in Olympus, the Protogenoi turned prison of the Underworld, Tartarus.
After entering Tartarus, Arthur headed straight for its deepest region, making his way to the special prison where a ginormous entity was sealed.
The Titan King of Time who'd once ruled this universe, his grandfather, Kronos.
The moment Arthur appeared, Kronos, bound all over by cosmic energy chains but still conscious, lifted his eyes, and his brows immediately furrowed.
"You…"
"Hi there, Grandpa. Long time no see."
Kronos' expression darkened at the sight of Arthur, which was understandable considering he wasn't exactly fond of Arthur's maternal side.
Arthur didn't know the full story, but Kronos seemed to hold some sort of animosity toward Lucifer.
