For those who didn't get a chance to pick up Archaia's Free Comic Book Day offering, Mouse Guard creator David Petersen has posted his contribution to the hardcover special, "Black Axe: The Tale of the Axe Trio."

"This is the 5th year I've done a FCBD story and the 4th in a row of this type," he writes on his blog. After my first offering, I started the tradition of opening each story with a younger version of a Mouse Guard character being told a morality tale which shows the audience a bit of insight into how that character became who they are as an adult mouse. This year's story is being told to Rand, and it deals with some mythic lore about the history of the Black Axe: The Tale of the Axe Trio."

Check out some of the story below, and visit Petersen's blog for the entire tale.
