Their speed was made all the most impressive once the Sea Serpents tried to follow the same path themselves. It might have looked an easy thing to scale, when they watched others do it, but the soil was crumbly, with the dirt being filled with sand. On the steepest sections, dry grasses offered to be handholds, but as soon as the slightest bit of weight was put on them, they'd come falling away, seeming likely to a too trusting a man with them, if he dared to commit more to the hold than he ought to have.
Steep it might have been, but it was not unnavigable. Concentration and effort was the requirement, and even the enemy raiders had managed to pass it, without a single casualty. It was just mindfulness, and the ability to not be swept up by the desire for excessive speed. The sort of recklessness that might make a man lose a foothold. It was easy enough to go tumbling down the cliff side, down onto the rocks below, after all.
