Noah stood before a massive, imposing door, its surface etched with intricate symbols and patterns. A holographic display materialized in front of him, presenting a single, enigmatic question:
[I have no beginning. I have no end.
I am always coming, but also always going.
I am essential to all life, yet can be destructive.
What am I?]
A sense of anticipation and challenge stirred within Noah. He knew this was more than just a riddle; it was a test, a gatekeeper to the next level.
Noah pondered the riddle, his mind racing. The words echoed in his head, each phrase a puzzle piece. He visualized the concepts, trying to find a common thread.
[I have no beginning. I have no end.] Time, perhaps? Or maybe something more abstract.
[I am always coming, but also always going.]
Time again, or maybe a natural force like wind or water.
[I am essential to all life, yet can be destructive.]
