The Turquoise Waters of the Piazza

I see a brigde over turquoise waters in the Piazza of Ventimiglia. However it seems the waters have dried.
That wont stop me, I've travelled a long way for this. 

I will paddle anyway.

ENCOUNTER WITH A STRANGER

There is a strange creature living in the depths of these waters.

It has lungs.

Hands.

A pentagonal spine.

and five eyes, one on each vertebrae:

He passes on wisedom to the messenger.
