Centurion Digod, nicknamed Half-Gallon, was an officer in the Dun Banner, a light cavalry in king Henselt of Kaedwen's army. His men included:

...Digod wasn't actually a fervent opponent of drinking on duty or in the camp, but more in order to save the barrel. The centurion's nickname had not come about by accident; the story went that, in favourable conditions, he was capable of knocking back a half-gallon of hooch, vigourously and with impressive speed.
