Maze
Okeanos punched and punched his way down, his arms turning into blurs as the shockwaves from his hits blasted sand away. The speed at which he excavated sand was almost frightening, every passing second getting him noticeably deeper and deeper underground.
'Wait! Wait!' said the genie. 'If you don't answer my riddle, you'll never break through the entrance! It's sealed by my magic!'
"We will see about that!" Okeanos shouted enthusiastically. After all, he was meant to be king of the seas. There was nothing he could not break. There was nothing that could be denied to him.
With a final burst of energy accentuating a punch, Okeanos smashed through to the bottom. There, over a dozen meters deep into the sand, his fist collided with solid grey rock. Upon the rock were carved the images of eyes.
Okeanos unleashed his Burst, creating an explosive aura of green energy around himself that prevented the sand from collapsing back in on him.
