Silas Darkmoon

Silas Darkmoon is the founder of the Darkmoon Faire, an exotic bunch of wandering showmen, who together celebrate the wondrous and mysterious idiosyncrasies found in Azeroth.

He, along with his faire, are the main characters of a graphic novel story Blood Runs Thicker in the Warcraft Legends series. It is shown in the comic that he will not allow violence to happen at the faire grounds, but also that when his friends, or, indeed his "family of freaks" are threatened, he has no qualms about using violence in the service of justice.

Inspiration
Silas Darkmoon may be a reference to Samson from the television series Carnivàle, played by Michael J. Anderson. Both characters are leaders of traveling carnivals, both dress similar and use a walking stick/cane, and both have similar stature. (Anderson has Osteogenesis Imperfecta, which made him very short.)
