Disclaimer: Neither C. S. Lewis nor I invented charades.
My first is a horn, to be one day availed
Of a note resolute and sublime,
Which duty by Aslan's decree is detailed
To a somnolent giant called Time.
My second is Eustace to Peter the King,
Queen Helen to Gale (you recall),
Prince Corin to Shasta (most marvelous thing!),
And Adam and Eve to them all.
My whole is a hard-headed Son of the Earth,
Of consummate oath-making skill,
Who, though Edmund made him a subject of mirth
At Cair Paravel's lately erosion-hewn firth,
Yet fifty times over has proved his true worth
(It wasn't his fault about Jill).
