        An idea was beginning to form in her mind.  The blocking ring on her horn was held on by magically-enhanced straps which could not be cut.  She knew all about them—hadn’t her mother had to wear one?  But the ring itself was a different matter.  It might not be enchanted at all.  After all, nopony would allow anypony to swing a chisel at their horn to cut it off—horns were sensitive.  A light, sawing motion might do the trick.
