“The ethereals are most fascinating indeed, but in my studies I have encountered another race of creatures who share many similarities with the ethereals. I feel we should speak of them as well--the brokers.
They share a nomadic nature, a desire to collect rare and unusual antiquities, and a penchant for trade.
Yet the brokers do not exist on Azeroth. Instead, they dwell in the Shadowlands... the land of death.”
