Radagst the Brown
In FotR, and the end of RotK, when the butterfly comes, could it not be said that the butterfly was Radagast?
In the LotR book, it is said:
"Radagast is, of course, a worthy wizard, a master of shapes and changes of hue."
Could PJ not say that the butterfly was Radagast, and that he had come with tidings to Orthanc?
Or, that it was an emissary of Radagast, sent to Orthanc with tiddings, and then later to signal the coming of the Eagles?
Think on this. 😎
