The entrance to the cave was quite big, but a troll was standing right in front of it, not allowing anyone to enter without being noticed by it. Alex and his group tried to look for another way to enter the cave, and they did find a smaller entrance, one that did not fit a troll. This other entrance was at the back part of the cave.
"Why is this entrance here?" Alex asked. It looked like an entrance for humans, which was useless considering the size of the trolls. There was no way they would use such a small entrance.
"Maybe this cave was once used by humans? There are plenty of mines in this part of the kingdom," ChangeGlassesYearly said. Alex nodded in agreement. "What you said makes sense. This place probably got abandoned for some reason, and the trolls decided to take it as their home."
That whole area had few humans and basically no farms or other types of buildings around it. So, the trolls were 'safe' there, away from the humans who could kill them.
