The destrier was a large, powerful horse known for its strength and ability to carry a heavily armored knight into battle. The courser, on the other hand, was a lighter and faster horse, often used for scouting and skirmishing.

No, fire-breathing dragons would not be biologically possible. The ability to breathe fire would require a biological mechanism to produce and expel a flammable substance, as well as a way to ignite it. There are no known biological systems that could accomplish this, and the energy required to produce and expel fire would be impractical for a living organism. Additionally, the heat and pressure from breathing fire would likely be harmful to the dragon's own body. Therefore, fire-breathing dragons are purely a product of mythology and fiction. **
