Jovian goes with the dragons from Ygg towards Amber.

The dragons put some distance between themselves and the great
Tree, and as they hit a comfortable altitude and pace Jovian sinks
his mental fingers into the modeling clay of Shadow.

A river, then. Under balmy air a silvery-green thread across the
distance, coming closer and growing into a gently curving
watercourse, broad and slow in its currents. The wings follow its
track as it narrows, valley closing in on it, yellow-brown scrub
growing thicker, acquiring bits of green that spread to a patchy
cover and then to a lush carpet below. The river speeds up in its
course, acquires curves and kinks and rapids here and there, the
froth of white water a mottling of texture from the dragons' height.

Trees march their way down from the rather less distant hills,
closing the valley a bit further around the river that guides the flight.
Old growth forests, deciduous and in full foliage, rich in their subtle
varying greens...and there, there too and one way over there, a
patch of deep crimson. The greenish hue of the river has deepened,
as has the river itself, dark blue with its silvery sunlit sheen. And
after a time the valley widens out again, the river coming down out
of hills to a floodplain and to a delta in the distance.

The wings sweep down, racing into the wind, the dragons taking
joy in the freshening seaward breeze - and a dot in the distance
becomes a boat, a large one, its great red paddlewheel sparking in
the sun as it churns. Whups.

Jovian guides Canareth in a banking turn, putting his tail to the river
and letting the crosswind pick up force - until the wind's dull roar
washes away the sound of the riverboat entirely. When the wings
wheel back toward the coast, the boat is gone - but at the cost of
some proper color in the land below, which has lost the quay that
was the riverboat's destination but gained an odd reddish cast to
the greenery of the landscape.

Over the fertile delta with its rich black soil and to the sea, out and
over low rolling waves. Beneath the rich cobalt surface schools of
fish are just barely visible...then dolphins leaping in higher waves
as the air cools, the coast a thin dull line in the distance. Then
they too are gone, the water darker, deeper, a high deck of clouds
rolling in to blanket the sky in uneven grey. Far below - farther now
as the wings have gained altitude, leaving thermals behind - a dark,
long-finned leviathan, nearly the length of some of the blue dragons,
breaches the surface, showing the long parallel lines of its
underside to the beasts in flight above.

Back toward shore then, racing with a tailwind. Dark cliffs heave
into view as a light rain falls. Birds dart in and out of crags in the
cliff face, raptors ranging for small fish. The rain lets up again as
the wings sail over the rocky crest, wind and sun melting crystal
blue holes in the cloud cover until it yields in a ragged line that
approaches and is gone again. The foliage below is a healthier
green again, the sky worlds closer to home with its yellow sun
sailing through rich cerulean....
