Weird Wednesday: A Disguise Might Have Been Preferable

To keep their daughter safe was not enough.
They could defend her while they were alive,
But one life each had they to lose. The stuff
They'd gotten, that would let their darling thrive
E'en after they were gone, so it was said
Would hide her very nature. She'd be fine
And healthy, but forever would seem dead
If only she held still -- though she'd be blind
And deaf  whene'er she did so. The exchange
Seemed worth it, for their enemies were strong.
So Icelyn grew up taking it. But, strange,
One day she dosed herself, but got it wrong,
And now lays lifeless? Senseless? Will she stay
Like this forever? No one now can say.
