"Based on what you encountered, that place is a cut-off piece of a higher world?"
Spirit Queen Yse inquired. We're now gathered back to the same room where we first planned the expedition. Now, with only the 6 of us and the Spirit King and Queen to listen to what we have discovered.
Rane and the other two already relayed what they experienced so they're not needed to be here anymore.
"Yes. The reason why you cannot enter is because there was some kind of illusion Formation that prevents Mortals from entering. However, if you become a Transcendent, you can go in and out of there without any problems. Just that, the place is too dangerous even for a Transcendent."
We only managed to explore one ruin and only at the entrance before we were pushed back by the old man and his overwhelming strength. What more would we encounter at the other landmarks that might be hiding something?
