Elemental mastery refers to the powers of the half-brothers, Lysaer s'Ilessid can control elemental Light, and Arithon s'Ffalenn can control elemental Shadow. These powers were bequeathed upon them as the result of a bride's dowry, when Talera s'Ahelas was wed to the King of Amroth.
It has been stated that the Fellowship are quite capable of these powers themselves, but that they would never do so, because what is possible does not always coincide with what is wiseTemplate:FootnoteLink.
The author has provided a clarification about what elemental mastery encompasses:
|On Talera's bridegift - you have mistakenly applied the term "elemental powers" to apply to the four elements, earth, air, fire and water. Light and Shadow do not fit into that catagory....nor should they. Elemental power, as Asandir would define it, means that the powers the two princes possess draw directly OFF OF the elements, and in short, influence all of them, without boundaries.
So the power of Light and Shadow do not correlate to earth, air, fire and water, but use the forces of all elements. What drives the powers of the elements - that would be source for the princes' abilities.Template:FootnoteLink
