Leto was the first baron of Plort, created by Triumvir Bast to rule over her cities. When Bast departed, the Edict of Bast gave him control over the north-westernmost lands of Konti-Nyuum.
In the early days of Plort, Leto wished to gain more prestige as the First Baron. He launched the Snowbound War against the Principality of El-Jheycom, but was repulsed and returned to his barony, his ambitions thwarted.
When Leto departed, his barony was split between those of Huinesoron and Laburnum.
