Aureate

Aureate or Golden Age (Latin, aureatus = golden) magicians were those of the era of John Uskglass, the Raven King. They habitually employed fairy-servants and the magical abilities of a number of them were very great, as Jonathan Strange once remarked:

"They persuaded sycamore and oak woods to join with them against their enemies; they made wives and servants for themselves out of flowers; they transformed themselves into mice, foxes, trees, rivers etc; they made ships out of cobwebs, houses out of rose-bushes..."[48]

Many of them left England in the King's company at the time of his departure.
