This makes reference to
R.A. Salvatore's
Drizzt books btw.
A title or rank given to the male of a Drow House who is responsible for tactics, martial arts training of the House's soldiers and protect the house of course.
Zaknafein was a Weapon Master and IIRC, Berg'Inyon Baenre was the Weapon Master of House Baenre.
Again
idiocy triumphs, Thanks to
wharfinger in pointing out my no reference of the author or what this is!
