After watching this video I have to say that I don't agree with AntonyC past belief. He treats Celestia as God(or did), Luna and Cadence stop that theory if alicorn is God how can there be 3 Gods. If you instead treat it like a Greek pantheon of gods the idea of 3 gods or 4 if we assume the changeling queen is a god in her own right then problem solved. Even gods in Greek literature get wounded by other gods nothing new for them they just don't die from wounds (most of the time). I dunno just a counter theory here.
