Elmer I Stuart (B. 1228 AFE/4187 BXC/2927 BNE - D. 1266 AFE/4149 BXC/2889 BNE) was King and 27th monarch of the Terran Empire and ruled from 1262 to 1266 AFE (4153 BXC/2893 BNE to 4149 BXC/2889 BNE), ruling over the empire for only four years before dying due to complications from inbreeding at the age of 38 and without heirs to the throne.
Better and more infamously known by the cognomens of Elmer the Ugly, Elmer the Broken, and more mockingly the Inbred King, the man's short reign was marked by lengthy periods of illiness and poor health that plagued him since he was a child. Furthermore, the man was both infertile and had the mental age of toddler, both as a result of generations worth of inbreeding started by Emalee III, making the question of succession a pressing concerning for the royal family, although Elmer I's short reign did put considerable more power in the hands of Parliament and the Prime Minister of the Terran Empire due to his inability to govern.
Ultimately the question of who would inherit the throne was put to rest long before Elmer I became king, as members of the House Stuart agreed that when Elmer I dies, his first cousin, Elmer II would became King of the Terran Empire. Although members did hope to make the Cousin Elmer the king instead of his sickly, inbreed cousin but due to the stubbornness of Alora I, Elmer I's mother-aunt, they ultimately could not force her to change who would succeed her when she died in 1262 AFE (4153 BXC/2893 BNE).
