The fact that one of the exhibitions was named 'Pre diluvium' could mean many different things. It all depended on what the system was, how it worked and where did this mysterious information came from, but being the archaeological geek he was, Uriel couldn't accept something as vague as that as evidence.
Instead of lingering on such matters, he tried to remember the vision where he saw Father of many nations, Dearest one and Water warlock at the top of a pyramid on 'El dorado'. Although it couldn't be considered hard evidence either, Uriel believed in the value of empiric evidence, not as proof but as means to further his research.
'If my theory that the mystical realm does exist somewhere and that the vision presented to me actually happened, then...' His thoughts were getting heavier and heavier as he muttered lots of historical facts, random theories and legends, until he remembered a pretty specific detail about his vision.
