I think so, the gentleman I was with seemed to be able to communicate to a limited degree. That said, we didn't see anyone else.
It was on wheel two, but it closed not too long after I went through it and it doesn't seem to still be there. But I don't think that means it is gone completely.
I understand, my companions are still there. I've been lingering near where the portal was in hopes that it will appear again and that I might be able to send them a message.
