The Caverns

Where Alph, the sacred river, ran
Through caverns measureless to man
Down to a sunless sea.
~ Samuel Taylor Coleridge, Kubla Khan

Reached via Lake Las Vegas, the ancient caverns beneath Nevada played host to curious inscribed walls and a great stone obelisk, prior to their combined destruction by Raiden and another unknown force. Scattered translations at the obelisk's base revealed it was a ceremony marker for the Dedication of the Fifth Gate. A strange shield was also recovered form the Caverns, bearing the symbol of a triangle with bowed sides. Although the deep pool's guardian, Ticutta was destroyed by Raiden, some thing else lurks in the dark lake, reptilian, and fond of giant bones.
