When the Son of Gotham grows old and gray,

a child shall be born of his ash,

though not of blood the same,

the bird will follow the bat,

as all is just for play,

but wait for the slash,

as it will no longer be a game,

when the birds go splat

What do you think of this, I had the idea a while ago but only got a little ways. when I found it in my notes I decided to add on and finish it I think it will be a good start to this book. (even if I don't normally write like this)
