Born as a slave, Draak, thanks to his intelligence, managed to escape by orchestrating a revolt. Later he worked as a mercenary.
Arriving in Waterdeep in 1478 DR, Draak found some of his slavers and decided that their best punishment was to become themselves slaves. He achieved this retribution, gaining a huge profit. Impressed, the Xanathar offered him a chance to work in the slaving sector of the the Xanathar's Guild and he accepted.
In 1479 DR, Draak was promoted to a lieutenant's position.
Draak supervised all the guild's activities involving slaving. He had few but very loyal subordinates. Normally he first contacted the buyer and later captured the slaves.
Draak was serious and gruff. He was an able leader that ruled using intimidation. He took pleasure from others' suffering. He had little loyalty toward the guild and cared nothing about its politics or the other lieutenants. He believed that very few beings deserved his respect and that all others were scum.
