Witch's Marsh Like a heathen clung to the homily

SEASHELL #5: Mineral-rich water has created heavy blooms and rich green vegetation.

The land became more verdant the further south Willow trekked. The marshland was hard for him to traverse at first, but he was light enough to avoid sinking in to the worst parts of it, and most he found his feet slick and wet, and he could live with that for the time being.
As he crept along, he came to a river and began to follow it. That proved to be the wrong thing to do — especially because he marched in a random direction, which happened to take him opposite to its flow — and soon enough there wasn't just mud and mire to contend with, but a tangle of blooming weeds and tall grasses the likes of which he'd never seen before.
It was the perfect combination of mineral-rich water from the bog and long hours of sunlight, he supposed. Willow liked to think of himself as some kind of naturalist, and as wild-grown as this place appeared, he was thrilled for the chance to study the overgrowth for new discoveries.
