A Seneschal is the right hand of the Prince, empowered to act in their stead. In Prince Kendrell's domain, the Seneschal holds a great amount of power: for 99% of cases, the Seneschal is the highest authority that fledglings, neonates, and younger ancillae need concern themselves with unless it is a matter of the Traditions.
Older and more respected ancillae, elders, and titled kindred conduct business directly with the Prince. The Seneschal also regularly reports summaries of their business to the Prince.
