The journey up the river isn't particularly difficult, though you do find yourselves a bit wet on a couple of occasions where the best way ahead proves to be wading in a shallow part of the river rather than fighting underbrush, and a few times the more keen-eyed among you notice elves watching you silently from the trees.
The mortal world isn't as vibrant as the Feywild, and things seem far less alive here, but it's still a beautiful journey. The afternoon sun sparkles off the river's water, a thousand points of glimmering light like fairy candles illuminating its translucent surface as you catch glimpses of fish swimming past beneath. The light breaks through the forest canopy, tinting the air with the heady green of spring. The song of the birds, if not as organized as in the feywild, is still a bright, cheerful thing, as petals from spring blossoms drift down overhead.
Salera's estimation of the journey time proves to be correct, and near sunset you hear faintly in the distance the sounds of chanting and a bizarre, guttural, deep form of singing.
