Back on Arcadia, at the 99th floor of the Tower just before the 100th floor, a woman dressed in a cover-all robe held her bow and cautiously entered the final room.

She entered the 100th floor searching for the man they call the strongest, and when she got to the top, she found no one, not even a monster.

The woman pulled down her mask and looked around at the wreckage Isaac left on his wake, again, "He beat the Tower, that explains why the monsters stopped spawning, hmmm?"

Walking around, she noticed a piece of paper next to a blood-stained floor. Picking it up, she read its contents and pulled down the mask that hid her face.

The ethereal beauty of an elf was shown to the world. Her apathetic demeanor radiated an ice-cold sharpness honed by the long life she led.

Her eyes that were said to be sharper than a sword read through the letter and sighed at the end of it all, "Disappearing for a month to another world. He didn't even consider telling me about it first hand?"

This elf was Lilia, one of the very few friends Isaac had back in this world. She was the most of Ancient of Elves whose lifespan already crossed the ten thousand years threshold.

She sighed, looking at the letter, "That guy is still making do all the work. I'll finish this quickly… a World Quest, huh." She said while reading through the World Mission she received thousands of years ago.

[Hunt the Black Abyssal Serpent under the World Tree's Roots.

Devour the Abyssal Heart and Conquer the Demonic Manifestations.]

"This is going to be exhausting." She said before yawning and keeping the letter away.

The letter's contents were simple:

[Lilia, I knew you'd arrive here searching for me in the odd chance that I do not return for one reason or the other. If you want to look for me, then finish your World Quest and come to this world. Maybe you'll finally find what you're searching for here.]

Lilia exited the room with a smile at her only friend's words.

'So he didn't stop searching.'
