Copping Squid by Michael Shea

....See the ice-cold, spinecrawlin, hair-stirrin truth?

....And he beheld a dizzying mosaic of lights flashing to life within the mighty pupil. A grand midnight vision crystallized: the whole of San Francisco Bay lay within the black orb, bordered by the whole bright oroboros of coastal lights . . .

He and Andre gazed on the vista, on the Bridges' glittering spines transecting it, all their lengths corpuscled with fleeing lights red and white. The two men gazed on the panorama and it drank their minds. Rooted, they inhabited its grandeur, even as it began a subtle distortion. The vista seemed tugged awry, torqued toward the very center of the giant's pupil. And within that grand, slow distortion, Ricky saw strange movements. Across the Bay Bridge, near its eastern end, the cargo cranes of West Oakland—tracked monsters, each on four mighty legs—raised and bowed their cabled booms in a dinosaurian salute—obeisance, or acclaim . . . while to their left, the giant tanks on Benecia's tarry hills, and the Richmond tanks too in the west, began a ponderous rotation on their bases, a slow spin like planets obeying the pupil's gathering vortex.

....He knew this being into whose view he'd come! Knew this monster was the King of a vast migration of titans across the eons of the countless Space-Times! Over the gale-swept universe they moved, these Great Old Ones. Across the cracked continents they trawled, they plundered! Worlds were the pastures that they grazed, and the broken bodies of whole races were the pavement that they trod!
