Frederick de Rolo

 was the father of Percival and Cassandra de Rolo and the lord of Whitestone. He was killed by the Briarwoods during their betrayal of the de Rolo family.

Delilah Briarwood claimed that the supposed "Uriel Bridge" to span the Shearing Channel was Frederick's idea, and that meeting with Uriel Tal'Dorei II to discuss the construction of such a bridge was just carrying out Frederick's wishes.
