Inside the cave was a massive portal that was glowing with a brownish light.
Dean, the ladies and the Storm Wolf were standing before the portal.
The portal was in the center of the cave it so big that it could accommodate about a hundred people stepping into it at once.
The portal was different from the rest that Dean had seen and stepped into. Apart from its humongous size the energy it was releasing was different from the other.
From just standing before it one could feel the presence of the other side. Meaning where the portal was leading to they could feel it.
"So this is the major portal leading to the Shadow Wolf main cave"
Dean said while looking at the ladies and the Storm Wolf before him.
He was filled with anticipation about what would happen once they stepped in they have struggled through their journey and be involved in a lot of battel but here they are standing strong.
