Thank you for your faith in me.
"Muthsera" is a title of high esteem, usually for landowning individuals in Morrowind. I have found only three examples of such a title being used, both in person and in literature. These are Muthseras Angaredhel, Rovone Arvel and Velando Omani.
"Sedura" is sometimes used to address landowning nobles, such as Sedura Hordalf Xyr.
"Ser" is used, although I cannot delineate under what circumstances due to it being used only once that I can find in Morrowind, and that is to address Ser Calissiah Vignum.
"Sera" and "Serjo" appear to be the common way to address a person without respect to his or her status on the social eschelon, with Sera being for the female and Serjo being for the male.
