They can be explored once a traveler has chosen to stay in your town :)
is there more than the tomb? just want to know if I need to buy like 80 more bell towers lol
After all the base dungeons have been cleared you can build a shrine, see the rest :)
was the protal supposed to close?
The portal closes if you fall or clear it. If you fall you can sacrifice another class to try again :)
i cleared it 3 times, but i sacrificed 3 of the classes in one go
okay then after it's cleared it closes :)
