Xanathar
Xanathar was originally simply known as The Eye before becoming a crime lord. He is an elderly, greedy, and paranoid Beholder from the Graypeaks Hive.
The Eye arrived in Skullport, already a slaver in search of a greater market. In time, his business and his organization grew. At one point, he re-organized his organization into a semi-autonomous model and retreated into the background, spreading rumors about his demise or retirement. Soon, most people forgot about the beholder slaver and in 1304 DR the Agents of the Eye were simply a large slaving ring in Skullport with no association with beholders. That was mainly operating in the Underdark due to the large destruction of the surface world during the disturbance.
When the new settlers arrived, the Eye started to gather information about the mysterious Xanathar Thieves' Guild, a powerful underground thieves guild coming over from the old world, and in time discovered that they were also led by a beholder, a beholder of a different hive. Thus the Eye decided to take control, by killing and taking the position of Xanathar. The Eye discovered all of the original Xanathar's secrets and at the same time manipulated another beholder, Uthh, into wanting to kill Xanathar. Eventually, Uthh fought Xanathar in his lair; Xanathar slew Uthh but was too weak to resist the surprise attack of the Eye. The Eye killed Xanathar and took his place as the leader of the Xanathar's Guild . The Eye pretended to be his predecessor but, in order to avoid problems, said that "Xanathar" was just a title. Afterward, the Eye gathered together his agents and the Xanathar's Guild.
This new guild now operates also from skull port as its base of operation and has expanded its slave trade recently to encompass breaking and training specialised units like the Kenkus for specialized mind-controlled servants. This idea was brought to the Xanathar by Klaus Hagen. However, the Xanathar does not know this and is assured the idea sprung from his own genius.
