Two days ago, the causeway literally disappeared right into the middle of a swamp. Ever since they've been carefully trudging along, trying to avoid the bogs on the way north. The pace was incredibly slow as they had to check their every step, lest they sink into the soft ground or fall into the dangerous waters. They had to go on foot and lead the horses, as the ground was too soft, and riding was risky. One misstep could get you swimming in the swamp.
