Royal cousins
So the one on the left is the son of Luna and Tirek. He was an accident but thats ok XD. His name is Eclipse and i might add on to it later. He is pretty tough but also a big softie. Eclipse loves almost everypony and most things, but if anything tries to hurt them, giant man horse will make them regret it. He is usually a muffin, but occasionally he has been known to use Luna's "royal we" tone of voice which is super scary. He may kinda accidentally hug friends and family so tight that they lose some magic, but he means well. Thats what you get with giant muscle arms. And a little evil magic. He can fly, but he weighs a ton so it is a lot of work even though his wings are huge. He usually just walks. Eclipse acts like a puppy and follows ponies around sometimes, and he is very loyal. And a bit of a ladies man. Not all ponies are into centaurs but dem muscles woa

The one on the right is the daughter of Celestia and who knows cuz i dont really ship her with anypony. Buuuuut her name is Daydream Bliss. She is very calm, cool, and collected. She is also pretty spacey and tired. Day falls asleep at really random moments all the time. It is a little concerning. Celestia has tried coffee and sugar but Daydream is just always tired. Other than that, she is confident, saying everything on her mind. and pretty hard-working. Mostly. Sometimes. Maybe one time. Ok she tries but she just falls asleep. She is very kind, and has a calming effect on whoever she is around. Day is pretty happy, and uses her magic to help ponies sleep and helps Princess Luna with ponies' dreams. Eclipse would help too, but he is very loud and would wake everypony up.

these guys were suuuuper fun to design. They both have flowing wavy hair like their moms cuz magic, and stuff woot. I didnt really want to make Eclipse a centaur, but im pretty happy with how he turned out!
