Well I was going to write about Conrad for this one, but your question is more immediately important!
Guide to the Territories pt4: The Black Axe
The term “The Black Axe” refers to one of two things, a legendary weapon, pictured above, and its legendary wielder. The story says that over 500 years ago, the greatest smith in the territories lost his family to predators. He poured all his grief and anger into his work and forged the deadliest weapon known to mouse-kind: The Black Axe. He gave it to the strongest and mightiest warrior of his day, who himself took the name The Black Axe.
Over the generations, the legends around the Axe have grown. He is said to be immortal, speak the language of every beast and creature in the Territories, and to have no rest in his mission to protect all of mouse society. He is a tragic hero, and the Axe itself is analogous to Excalibur in how it bestows incredible power but your life is no longer your own.
Book spoiler/mild Summer campaign spoiler:What we know as readers, and Francisca suspects, is that the Axe is real and survives to this day. It has been passed down over the generations and the impossible skills attributed to the great warrior are the sum total of those of its many holders, plus the exaggeration of a re-told tale. At the time of our game it belongs to an aging hermit named Celanawe. He appears in all three volumes of the comic The third is a prequel about how he came to take the weapon and the name. Below is Celanawe in his younger days.
