As they walked, Libera couldn't help but ask, "My lord, how did you pass the Gatekeeper's riddles? The Book of Eternity claims that the riddles ask questions about the very essence of life."
Karl chuckled. Pffftt… anyone without knowledge of modern internet memes wouldn't be able to answer that. Only humans from modern Earth could. A thought then hit him, making him pause. He repeated the phrase in his mind: anyone except modern humans, but there's only me, isn't there? He began to wonder. Did humans build this place? Or is this world I'm in just Earth, but so far in the future that humans no longer exist? This is a piece of history I have to uncover.
He then answered Libera, "The riddles were not about life's deep, complicated truths. They were, in fact, based on sarcasm and cultural references."
"So it's just jokes?" Libera asked.
Primarily, yes," Karl replied, wanting to avoid a lengthy explanation.
