A question for Riot games

What are made of, and if they are leather, would be committing some sort of sacrilege? Can we also assume there are cows on Runeterra? I want to know, like are there steaks? Would Runterra have a McDonalds like food chain if an opportunity was given? And when was named, why was it named infinity edge? It technically has Two edges, as the only thing with infinity edges are spheres, so shouldn't it be a circle? Any ways, I hope these questions only wasted a bit of your time. Please respond ~etsa
