Every year each of Twelve Contrade of Remora have a horsemaster in charge with planning and preparing the horse and the jockey who will participate in the Stellata. The horsemasters are addressed by the title of Capitano during the Stellata and will meet with the horsemasters of allied Twelfths to discuss strategy.
Outside of the Stellata, the horsemasters are responsible for breeding and racing horses to run in the Stellata.
The Ram[]

- Gianandrea[2]
The Twins[]
- Riccardo[1], the Horsemaster of the Twins, hosts the Air Twelfths (the Scales and the Water-Carrier) during the strategy meetings for the Stellata. As the Horsemaster of the Twelfth affiliated with Remora, his Twelfth along with that of the Lady have won the majority of the Stellata races over the past fifteen years thanks to the influence of the di Chimici family. He is on good terms with the Horsemaster for the Lady.

As the Horsemaster of the Lady, the Twelfth associated with Giglia, Emilio is on good terms with the Twins' Horsemaster, Riccardo; both their Twelfths have won the majority of the Stellata for the past few years thanks to the influence of the di Chimici.
