Lounging around in the Cantina, Kolburn kept a watchful, yet unassuming eye on those around him as he finished the last morsels of what passed for a meal in this joint. Brushing off the crumbs, he glanced round, careful not to make eye contact with any of the other patrons who might later remember him as he made his way unobserved to the entrance and out into the cold of the port. He would come back and pay off his mounting tab, when he next came across a few credits, or found another odd job. After all, he wasn’t completely without his honour, unlike some people.
Orcish currency is derived from glass beads. The art of glassworking is well beyond them, but perhaps the orcs have something of value to the civilized races, such as animal pelts, and well made axes, and bows. The humans trade beads for the goods, and the orcs will trade the beads amongst themselves as a form of their own currency. Perhaps they value blood red beads above all others, or animistic orcs favor beads in the colors of their gods.
