A short, dark-bearded human wizard that known to most as "Glasstaff" for magic staff made of glass.  Iarno was initially a member of the Lords' Alliance, who was sent to the town of Phandalin to establish constabulary (as the town did not have a powerful authority).     However, when he arrived in Phandaling he organized a group of thugs known as the "Redbrand," and as it turned out, was in alliance with the Black Spider.
