But also, this is just A.K. Yearling hate. She's pillaged so many cultural artifacts so they can just sit in boxes in her house (or museums), and destroyed major cultural centres in the process. Those zigurats weren't abandoned, there were ponies guarding it. This drawing was me venting about her and standing with Fluttershy in that one episode.
