I was messing around with
cheat codes on Xenoblade chronicles 3DS, And found two rooms that are not accessible at all after the bionis moved. The throne room and the princess's chamber in alcamoth. Using infinite jump far enough away to not hit the death barrier, I was able to enter the throne room and the princess's chamber. The throne room had several telethia and a heart-heart prompt, same thing applied to the princess's chamber. We can't ever access this after the bionis had moved, so I wonder why they had made these two rooms with telethia in them. The heart-heart prompts are the same as it was before the bionis moved.
