As he learned the different fjords, he found he had his favorites. The Florentine, directly southeast of Da Vinci, was a pretty oval of water; a walk along the low bluffs overlooking it was continuously picturesque. Thick grass grew like a mat over these bluffs, they looked like Sax’s image of the Irish coast. The land’s edges were softening as soil and flora began to fill in the cracks, holding to mounds that defied the angle of repose, so that one walked over pads of ground, swelling between the sharp teeth of still-bare rocks.

Clouds poured inland from the sea to the north, and the rain fell, steady deluges that soaked everything. The day after a storm like that the air steamed, the land gurgled and dripped, and every step off bare rock was a boggy squish. Heath, moor, bog. Gnarly little forests in the low grabens. A quick brown fox, seen out of the corner of the eye as it dashed behind a sierra juniper. Away from him, after something? No way to know. On business of its own. Waves striking the sea cliffs bounced back outward, creating interference patterns with the incoming waves that could have come right out of a physics wave tank: so beautiful. And so strange, that the world should conform so well to mathematical formulation. The unreasonable effectiveness of math; it was at the heart of the great unexplainable.

Every sunset was different, as a result of the residual fines in the upper atmosphere. These lofted so high that they were often illuminated by the sun long after everything else was in twilight’s great shadow. So Sax would sit on the western sea cliff, rapt through the setting of the sun, then stay through the hour of twilight, watching the sky colors change as the sun’s shadow rose up, until all the sky was black; and then sometimes there would appear noctilucent clouds, thirty kilometers above the planet, broad streaks gleaming like abalone shells.

The pewter sky of a hazy day. The florid sunset in a hard blow. The warmth of the sun on his skin, at peace in a windless late afternoon. The patterns of waves on the sea below. The feel of the wind, the look of it.
