Mari'thur (male) or Marah'ni (female) is the thalassian equivalent title to Marquess in common and is a title of higher nobility within the Kingdom of Quel'Thalas. Mari'thur's historically were given large provinces of land boardering neighborhood kingdoms of Quel'Thalas and were expected to upkeep a contingent of armed forces, defend and fortify against potentially hostile neighbors and maintain regional safety against aggressive neighbors. This slight distinction is what raises the title of Mari'thur above the more common title of Esarthis. Mari'thur generally oversee entire provinces of thalassian land included cities, towns, many villages and hamlets. Their income generally allows for a large castle or massive estate and they are expected to fund, train, and equip a standing provincial army at all times. Mari'thur generally is a hereditary title, although the High King of Quel'Thalas may bestow this rank of any lesser noble. Mari'thur is also a high enough rank to garantuee a place within the Thalassian Senate, primarily in its House of Nobles.
