To the “contains only the following identifying information about them” list in The Masquerade, add:-

* Their Mask

And add a paragraph after the list:-

Each Elector’s Mask is chosen afresh for each Masquerade by the Doge, in a secretly random manner from the following list: Arlecchino, Bauta, Columbina, Medico, Moretta, Pantalone, Volto and Zanni. However, if an Elector is the Winnower, they always wear a Medico mask; if they have a Faction of “-” and are not the Winnower, they always wear an Arlecchino mask; if they have a Campaign of Gerontocracy, a Faction other than “-” and are not the Winnower, they always wear a Pantalone Mask.
