One of my challenges I've put a lot of thought into is transportation in the elven kingdom because it covers a wide expanse of land and the regents need to travel quickly as they have meetings at the regents board of governors.
At this stage of development they do not have long-distance communication only carrier hawk or something to that effect – “Dispatch a Ceryx over to Quinberry at once with this message.”
The ceryx is a relatively small bird with a large beak. Averaging 19 inches from head to tail with a 3 foot wingspan. The ceryx live in harmony with elves in the elven villages. A very populous species, they are everywhere and make great helpers.
