“Tartarus.” Cosine mused, her headfeathers twitching thoughtfully. “It does ring a bell. Dungeons certainly seem like something one would want in the Underworld.” There might be something in the library.
Alva smiled a little, the library, a word she had only learned since coming to the rooms of Cosine and Ankou. She couldn’t even read, though her goddess could so between them it might work. She followed the goddess down the empty halls to the grand library. She really had never seen anything like it, and that was even since she had been in the amazing Pantheon. The doors were as tall as her home back in her own world and opened into a space so vast it was hard to comprehend it.
“This is only the tip of the iceberg. I am not sure any of us, not even Endiovar and Kios know all that lies within these doors.”
Alva realised that she must have been gawping. Not that she was surprised by the goddess’s words, it seemed that nothing was really as it seemed within the walls of the Pantheon. She followed the goddess through the main atrium and through one of the many doors that led off of it, hoping that Cosine knew where she was going, it seemed like the sort of place that you could be lost, never to be found again.

"I have found some books just to the left here that detail some mythology of the pantheon, world tree and others. There might be something about the Underworld here." Cosine led her through two other rooms full of books and into another that was circular. The shelves were on two levels, the lower that they were standing on, then a spiral staircase led to an upper level of shelves. There were many books lining the shelves, though gaps where others had been removed for renovations.

"Now, Underworld."

Alva watched the Number goddess with interest as she stared at the books, almost as though she could tell what was in each one without looking. She peered at the books next to her and noticed the numbers printed on the spines of leather.

"Ah, ha." Number walked across the room, stood on tiptoes and eased a rather large book off the shelf, she carried it, not caring about the dust that had kicked up and was swirling around them. Alva felt a tickle at the back of her nose and sneezed loudly.

She watched the Number goddess smirk and moved over to stand next to her.

"Obviously this isn't definitive information on the Underworld, but it might provide some enlightenment into what was."

Alva nodded and looked down at the old tome. The writing seemed to be squiggles, nothing that she could understand, though she could not read. She hoped Val would be able to.
The goddess could indeed process the squiggles.
