Insidious Adversary

Sunny sighed heavily, then subtly studied the world through his shadows. There was no danger around them. Everything seemed fine. 

That said, his intuition was indeed telling him… something. It was not exactly ringing an alarm, but there was an eerie sensation at the back of his mind. 

He rose to his feet and studied the Great River with his own two eyes. 

After a few moments, Sunny asked:

"What is it? I don't see anything."

Cassie did not move, her frown deepening. The waves rustled as they brushed against the hull of the ship. The sails rippled in the wind. 

Raising a hand, she touched her cheek briefly, then said somberly:

"I feel… strange. As if I'm drunk."

Sunny stared at her wordlessly. 

"Huh?"

The blind girl grimaced.
