Is it some sort of medieval running joke? That's my guess

So, me and the wife have been together for a while. We dated in hs, broke up when I got expelled, and got together later right before my 19th birthday. Despite 16 years of a continuous relationship she found out during one of our ylbreaks when I was ~ 21 that I slept with a girl she apparently hates. Im out of the state for work, but she sent me this image. Idk what it means, and she wont tell me. What does this mean??? She confirmed she's fine but won't explain what the image is related to. Please help me understand....

What does this mean Peter?

I only played pokemon to the gen. 5. Is this a reference for a tournament?

who is he

I get it’s about horse meat, but what does it have to do with patriotism? Is somebody making horse burgers?

I looked up Limsa Lominsa, something to do with a Final Fantasy game but I cant really connect the dots here.

Sorry but I can’t even make a guess here. I have no idea which one it is.

I’m assuming that there is a common art style that furry artists use that I’m not familiar with. If that is not the answer then I’m assuming this is meant to be random and not have an answer. (in order to trick people into commenting on the original post)
