Dune - Waters

"Tell me about the waters of your homeworld, Usul."
Another moment from Dune, using old character designs.

Paul's face is disrupted by the ripples, his vision of himself and his own future is disturbed.
He's standing in front of a vision of his future self (sideways skull), the worst possible future beginning to haunt him.
