The footsteps weren't heading directly in the enemies territory, so Jason could tell that they didn't make any obvious mistakes. Still, he crossed a considerable distance, but he didn't find signs of civilization, so his allies probably felt troubled since they didn't find any sources of food as well.
"What they did do this time…" Jason thought while looking around.
Jason's allies couldn't have vanished without a reason. In a world filled with hidden dangers and lurking threats, their sudden disappearance points to a precise and orchestrated action. The most plausible explanation is that they were ambushed by enemies. This wouldn't be a random occurrence but rather a premeditated assault carried out with precision and stealth.
