I went away in my head, into a book. That was where I went whenever real life was too hard or too inflexible. - Neil Gaiman

Stories, like people and butterflies and songbirds' eggs and human hearts and dreams, are also fragile things, made up of nothing stronger or more lasting than twenty-six letters and a handful of punctuation marks. Or they are words on the air, composed of sounds and ideas-abstract, invisible, gone once they've been spoken-and what could be more frail than that? But some stories, small, simple ones about setting out on adventures or people doing wonders, tales of miracles and monsters, have outlasted all the people who told them, and some of them have outlasted the lands in which they were created.

On the battlefield called Vigrid, the gods will fall in battle with the frost giants, and the frost giants will fall in battle with the gods.The undead troops from Hel will litter the ground in their final deaths, and the noble Einherjar will lie beside them on the frozen ground, all of the them dead for the last time, beneath the lifeless misty sky, never to rise again, never to wake and fight.

That's the trouble with living things. Don't last very long. Kittens one day, old cats the next. And then just memories. And the memories fade and blend and smudge together.
