Chapter 6: Echo Cavern

Lanterns of Eternal Flame were anchored in the walls of the mass cave system. Crumbled stalagmites cluttered the floor.

The group changed into their rubber sandals.

A rock bounced off Grover's sandal, flying against the wall. The smack from the collision echoed twice in the cavern than a distant crash followed. A sharp rock formation fell from the noise.

Both demi-gods held a finger to their lips, needing silence. Grover paled then looked sheepish for causing the noise.

The cavern was dusty; even while tip toeing through it they stirred up dust. The ground was uneven.

Grover's brown eyes nearly popped out of his head as he tried to stop from sneezing.

They could literally see the light at the end of the tunnel when Grover could not hold his sneeze in any longer. "Achoo…" he had the decency to blush as his sneeze echoed multiple times. Stalagmites came crashing down, ready to impale the heroes.

Percy pushed Annabeth to the ground as he fell so they both avoided impalement. They could not run in a straight line, but Grover used his legs to jump longer spaces.

"I am sorry, guys. I just could not hold it anymore," Grover hoped they were not mad at him.

The demi-gods shrugged, out of breath and bruised.
