Meeting The Elder Marble.
"Let him in".
As soon as this voice reverberated, the shark guard hovered in the water while making its body straighter as it obediently opened a path to let Sebastian through, leaving him dumbfounded.
"How did the elder know I was coming?" Sebastian asked this in his mind but it did not slow him down as he was already on his way inside.
Going through the entrance, he immediately noticed the difference between this chamber and other chambers in the cave.
Apart from the more perfect caving craftmanship on par with that in the throne chamber, inside was a long spiraling passageway that led downward. The water in this passageway flowed faster, just like water rapids.
Seeing this gave Sebastian weird vibes but it could not stop him as he continued inside the passageway.
Whoosh!
