This entry draws information from the fictional Dune universe, as created by Frank Herbert. However, prescience may actually exist as a psionic phenomenon.
Much more needs to be added. E.g. quotes from Paul and Leto, and examples such as Piter De Vries forays into prescience.
Cassandra, the daughter of King Priam of Troy and Hecuba, was prescient, for all the good it did her.
