Destiny — Blaze Ward

When Brak destroys his mighty axe Woodchuck in battle against an evil necromancer, Sleipnir undertakes to find him a replacement.

Nobody counts on the Gods themselves taking an interest in the outcome, nor the path that opens for a half-wit half-troll warrior.

Be sure to read the Brak stories:
Meat Shield
The Popcorn Kitten
Feet of Clay
