Inside a crate on level 1, you find
An ancient scroll of wood and parchment, inlaid with gold, unmistakably from Ancient Egypt. Anyone with the talents to do so, prior to opening, will be able to confirm its authenticity and date it back to about 6,000 BC.
If opened delicately, it reads, in current era American English;
"Dear diary...
LOL these 'e jip shans' don't even know what emoji r!! can u beleve that?? SMH! I GUESS i can teech them. i mean, they keep dropping 2 there knees n junk and doing evrything i tell them 2, right? :) its the least I can do. LOL"
After reading the scroll, you begin to notice that all hieroglyphics are now written entirely in modern emoji. When did it change? Or have they always been that way? You're pretty sure Anubis was not represented by a poop and dog emoji... If you confer with anyone, they will be certain that nothing is different. If they are shown the scroll, they will suffer similar doubts.
