Congratulations on your fertility, princesses. Equestria’s needed more than two alicorns. However, ^***please stop having children!***^ Two alicorns each year is too many!

Prince Nubes leaves weather teams idle. Historically, fewer ponies have solar cutie marks now. Ponies find new interpretations of their destinies, then another alicorn appears!

Growing alicorns eat twenty times what ponies do. Your highnesses currently eat fifty times as much. The alicorn of fields solved this, but it’s causing us farmers difficulties!

Princess Celestia blushed, glancing beneath the letter at the newest alicorn inside her. She looked to Princess Luna, with a foal on her lap and another in her lap. “Luna, how old is Nubes, your eldest?”

“Fifty years, practically foal.”

From two to one hundred alicorns. “Luna, are we having too many foals?”

“Nay. Ponies should lead lives of leisure, as in days of yore.”

Luna’s foal was adorable. “Just a few more.”
