It wasn't until much later that we figured out what had actually happened.
You see, all of Juliana's daggers were coated in the venom of the giant two-headed serpent we hunted on the day we set up camp after escaping the Temple of the First Rebellion.
As soon as we killed that serpent, the mist began to grow dense, slowly swallowing the entire region.
After laying out those facts, it was easy to deduce that the two-headed serpent and the Mist Monster were probably natural enemies.
They were two apex predators locked in a war for dominance — each keeping the other in check.
For whatever reason, the serpent's poison had evolved to corrode the intangible.
This meant the serpent was the only beast that could truly wound the Mist Monster, preventing it from expanding its hunting ground, even though it was the weaker one.
