Cornis

Cornis, Emperor Consort of the Imperial Commonwealth, Emperor Consort of Kordowyn, King Consort of Auchinmore, Grand Prince of Ceredigion, Count of Castell-nedd, Count of Talgarth, and Baron of Aberteifi, Prince of the Viseroths, Duke of Novocorinolaudum is the second son of King Daelin I, and is the Emperor Consort of Kordowyn due to his marriage to Empress Charlotte
Cornis was born with his twin brother Basilean on the 18th June, 243. Initially, it was believed the two were identical twins, and as such small marks denoting "1" and "2" were tattooed onto their backs. Unlike his elder brother, Cornis was a quiet child and has been compared to his father; reserved, highly literate, and shrewd.
As part of an agreement reached between his father and Llywelyn I of Kordowyn, Cornis was sent to receive an education in Kordowyn much like his aunt, Mila. 
Cornis kept a low profile in Kordowyn, unless one counts the time he advocated for the violent overthrow of his brother by the Hybretian people, and married Empress Charlotte in April of 264, inheriting many of her titles as her Consort. He was also made Grand Prince of Ceredigion. He is the first Emperor Consort in Kordynian history.
In 265, his wife gave birth to their son, Llywelyn Milos ap Cornis Caestor, who is the heir to the Commonwealth Throne.
