David I of Cattala

King David I of House Celestine was the fifth King of Cattala, as the great-great-grandson of the monarchy's founder, King Roger Celestine. King David was the first King to institute social and economic reforms and the first King to have previously served as Chancellor.

David remains one of the longest reigning monarchs in national history, ruling for 49 years. His controversial marriage to second cousin Lady Annabel Celestine caused tension and rifts in the family.
