As Simon witnessed all the scenes, he felt his body revert back to its physical self and instinctively knew that the historia had ended. He was finally aware of the events, the trail was trying to convey and at the same time got a glimpse of what had occurred here in the past.
However, even when the Historia ended, there was still a concern in him that still remained. His concern was related to none other than the hand which now had the self-consciousness of the being.
No, calling him being was inappropriate when he knew its name. Ozymandias, that should be the name of the entity that had fought with Yela and also the source of all the negative curse energy inside the tomb.
After Simon sorted out his thoughts, he finally laid his eyes on what lay in front of him. The wide pristine hall with the statue of a six winged angel in the middle, was something that he had seen in the historia.
