OTOH, just like you find in certain parts of the world of today, the leaders of Egypt were prickly sorts, and did occasionally try to eradicate records of less favorable events.
Still, even if Frogjira didn’t exist, it makes fo both a nice bit of inspiration for adventure design. Not just in and of itself, but also from the standpoint of finding inspiration in Re-imagining the stories, legends and myths of old.
For example, with Stargate, Star Trek, Red Dwarf, Arthur Clarke, and Von Däniken in mind, I took the stories of the fae of Underhill and made them crashlanded Greys whose use of tech like stasis fields, multidimesional construction and solid-light holography to become the “Elves” of one campaign setting while they waited for rescue.
IOW, the familiar mythology and faith stories we have can be mined for new ideas, if we just think that:
1) what they handed down to us was as close as they could get to describing things they didn’t have the vocabulary to depict with accuracy, and
2) maybe the stuff they wrote down was accurately depicted, and subsequent writers “corrected” what they assumed to be errors.
