Roger, known as the Reveler, was a duke of Toussaint and the lover of Countess de Stay'cherr, living in the second half of 12th century. As his nickname suggests, he was no teetotaler and stories of his alcohol-fueled ramps number today among the most cherished of traditional duchy's tales. Maybe it was the bottles of Sangreal and Est Est, maybe something else, but the duke decided to built several fortresses like Fort Ussar and Mont Crane Castle to protect his subjects against highlanders from Mount Gorgon even though such folk never existed. However most of these castles became ruins shortly after the death of the ruler because architects loved to drink too.
Judging by chronology, he could be the husband of Duchess Carolina Roberta.
