The Warlock Knights were the lords of Vaasa in the 15th century DR. The knights were ruled by the leader of the Ironfell Council, the Voice of Telos. Warlock Knights were the elite fighting force of that realm and only a few were considered worthy to join the ranks. All Warlock Knights wore a simple ring made of ironfell and many practiced ritual magic using their rings. It was not uncommon for Warlock Knights to be accompanied by Bound Ones, or nishaadhri, who were wizards who swore them fealty in exchange for the freedom to pursue their magical study.
