Hi,
Here is the history of my 8 visits inside that cave:
1st visit) coming from Teledahn, I heard the 1st speech (I stopped it before it ends), I deliberately crashed my game because when I jumped into the void, I was thrown in darkness. I had the possibility to touch my Relto book but like we all know we cannot "Relto out by linking with our book" in such age.
2nd visit) coming from Kemo, I didn't hear any speech at all, I jumped and came back to my Relto.
3rd visit) coming from Kadish, I heard the 2nd speech (I stopped it before it ends), I jumped and came back to my Relto.
4th visit) coming from Gahreesen, I heard the 3rd speech..."You returned again, returned to hear more, returned for a third pillar..." (I stopped it before it ends) "Say what?, a third pillar? How come a third pillar, i'm already at the 4th one!" (my thoughts) I jumped and came back to my Relto.
5th visit) coming from Teledahn, I heard the 4th speech even though I had disabled the speech in the 1st visit. I returned the pillar, jumped in the void & came back to my Relto
6th, 7th & 8th visits) all went accordingly to what I've expected.
