The heat was oppressive. Sweat gathered on Stark's dark face. His shirt stuck to his back. The air was heavy with moisture, tainted with the muddy fecundity of the land that brooded westward behind the eternal fog.

There was something ominous about the sea itself. Even on its own world, the Red Sea is hardly more than legend.
