"They can see through illusions?"
"Indeed. See these mists? It's an illusion that a monster produces to hide its presence from its predators and aggressors. I haven't seen it personally, but most of the adventurers who have traveled deep into this place told them it was a weak monster and herbivore that lives in a colony allowing them to create a massive mist that covers the whole place as a result... You can say that this place is the perfect place for these Treants to live in as they can use the mist to hide and live peacefully without being attacked and killed by adventurers as they would be more busy trying to find the right way and avoid getting lost from the mist," Zena explained.
"So that's why the mist seems pretty much feels abnormal. It isn't cold enough for the mist to form and roll in and trees are not in sight yet the place is filled with this foggy mist. But if that is the case, these mist shouldn't be real right?"
