Yes, but if the combined weight of 2,500 years of scientific evidence has failed to turn up credible evidence of psionic Aslans, no credible expert would clain that it was a well-known, albeit rare, phenomenon, and if psionic Aslans were known, albeit rare, no credible expert will claim that's it's unknown. One of the two remains credible only until the matter is settled. Which a single statement in the authorial voice will do. At that point Shrödinger's Expert dissapears in a cloud of logic.
I have seen an Elephant and the Statue of Liberty both made to disappear, yet in spite of the overwhelming evidence, I still refuse to view Magic as real and hold onto the belief that it is all Hocus Pocus tricks.
Among a race in which Psions hold the same level of scientific verification as Earth Ninja, how can one argue so vehemently FOR PROOF OF PSIONICS being common knowledge. We have had 6000 years of recorded human history to proove of disprove magic, religion and ESP, yet the existance of all three is still debated.
Surely Psionic Aslan Assasins deserve at least a little doubt among the general public.
