Lord Charles Rinforte was the Prefect of the Cassiline Brotherhood during Joscelin Verreuil's time as a Cassiline Brother. Orphans taken into the Brotherhood always were adopted into the prefect's household and took his name. Because of the longevity of Lord Rinforte's service, many Cassilines were adopted as his foster sons and bore his name, including Brys nó Rinforte, Léon nó Rinforte, and David de Rocaille nó Rinforte.
Anafiel Delaunay de Montrève wrote to Rinforte to ask that he assign a Brother to guard his foster daughter Phèdre nó Delaunay during her work as a Servant of Naamah and spy. Lord Rinforte assigned Joscelin, a young Cassiline in his early twenties, to serve Phèdre. When Joscelin chose his duty and loyalty towards her over his vow of chastity, the Prefect declared him anathema.
A year later, Lord Rinforte was seriously ill and dying due to a long wasting sickness. Not long after, he died, and Lord Calval replaced him as Prefect.
