Good question, <race>. In my younger days I was footloose and fancy free without a care in the world. In those days I would sing in a barber shop quartet out of Stormwind known as the Four Dons. That's where I learned how to craft the Bonescythe Digs.
Yes, Bonescythe. You see, it was our tenor, an ornery fellow known as Don Julio, who got me started on the whole thing. In his travels throughout Lordaeron, Don Julio picked up many interesting skills, one of them being the ability to take the bones of fallen Scourge and fashion them into a lethal set of leather armor - perfectly suited for an assassin.
