an invisibility charm works like this:

slow, the first time, uncertain still of how

you will fit together, who will warp

and who will weft, whether you are

a trick of the light or the human

eye, but how hopeless are you

the first time you must disappear?

desperation suffices. spellcraft

is eased along both by necessity

and knowing that illusions are lies

like anything else. before you begin

to vanish, you might try to wear 

another skin, which is also only

lying, but it hurts. i would rather

not be seen. make no promise

between witches, for we can give

you nothing but yourself, but if 

you draw yourself a cloak of night, we 

will hold you in the shadows and call

fireflies when you are ready

to be home.
