The nature quote

"Beware of an invasion from the outside"

Leads to the conclusion that creatures from another world or dimension may, as has put it, "Cross over," into Runeterra. I feel that if it were to directly refer to content such as what you have mentioned, it would say something leaning in the direction of "Beware of cinematics," but less revealing than that. Maybe "Make sure you cook some popcorn."
