balls of fire burning in the blackspace

Imagine for a second a river of fire.
You've probably thought of something like a river a lava. That's not what I want exactly. That's really just a river of rock. Really hot rock, and it is sometimes on fire, but it's not quite a river of fire.
Now, imagine a river of fire. A river of flames. It rushes and roars like a jet engine. Buffeted from side to side by the rocks. The torrent of fire rushes along the winding floor of the canyon. Wide curves seem to be straining to hold the fire in it's path while sharper corners violently deflect and redirect the river int a new direction. From above, the chared rock and soot that extend halfway up the canyon walls make the canyon look deeper than it really is. The river is brilliant red against the black backdrop, but in the sunlight it seems to flicker. The smell of burning permeates everything, and the breeze dose not drive it away. At night, though, the wind shifts, bringing sweet. The dirtiness of the soot is invisible in the black of the night and the clouds all around are lit by a red glow from below. The river is a ribbon of violent red weaving through the canyon bellow and eventually out of sight around a bend. Whatever the river does not illuminate is pure darkness.
