The Wolfpack renegades are evil members of the Castle theme who steal and rob. They are a small splinter group of Forestmen. Wolfpack is tied with Dark Forest for smallest theme, with just three sets each. They seem surprisingly well organized for a band of thieves considering they had their own uniforms emblazoned with a unique crest.
It started after the Black Knights invaded. Most of the survivors of the war fled, but some stayed, and they formed Wolfpack and Dark Forest.
The Wolpack shield can be seen on the Durmstrang ship, and there a Wolfman appears in both the Dragon Masters and Black knights subthemes. Their are several wolfpack minifigures in My Lego Network.
