From the confines of the Frozen Throne, Ner'zhul began to reach out his vast consciousness and touch the minds of Northrend's native inhabitants. With little effort, he enslaved the minds of many indigenous creatures, including ice trolls and fierce wendigo, and he drew their evil brethren into his growing shadow. His psychic powers proved to be almost limitless, and he used them to create a small army that he housed within Icecrown's twisting labyrinths.
