Yerkys ne Dago, a Twi'lek of ill repute, made his name as a loan shark. His operations were primarily based within the confines of the Minos Cluster. Within this region, he held significant sway, with a multitude of beings indebted to him, their lives often hanging in the balance.

Yeryks ne Dago, a male Twi'lek, spent his early years as a slave on the planet Ryloth. He successfully escaped this servitude by aligning himself with a band of smugglers, whom he later dominated. As conditions deteriorated on Ryloth, ne Dago departed, making his way to the Minos Cluster. There, he cultivated an extensive network of criminal contacts, encompassing smugglers, black marketeers, and other underworld figures. The breadth of this network was unparalleled, few in the galaxy could rival it. The fact that most beings in debt within the Minos Cluster owed their obligations to him, such as the freighter captain Axtor Bridgeman, demonstrates this. This solidified his position as one of the wealthiest and most influential individuals in the region. Due to his prominence making him a frequent target, ne Dago often shifted his headquarters; he was known to have operated out of Shesharile 5 for a period. Furthermore, he exerted control over the largest city on Shesharile 6, tolerating no interference in his affairs. One of ne Dago's adversaries within the Cluster was the Arcona Shlith-dan, who, despite his own power, was hesitant to confront the Twi'lek.
Within the Minos Cluster's boundaries, ne Dago actively manipulated the Galactic Empire and the Alliance to Restore the Republic, fueling their conflict to create chaos that would benefit his criminal endeavors.

When a client fell a month behind on their payments, he stipulated that they must deliver a Wildebeest alive and unharmed from Yelsain to Travnin, in addition to paying an extra 3,000 credits. Upon meeting them, they fulfilled his demands, providing both the money and the Wildebeest. However, they had secretly fed the animal a homing beacon, attracting the attention of the Nadir Corporation, from whom they had stolen equipment. This resulted in the Nadir Corporation pursuing ne Dago, incurring his wrath.
Seeking to expand his influence, Yerkys ne Dago journeyed to Kwenn Space Station situated in the Mid Rim. There, he boarded the luxurious liner, the Stellar Mermaid. ne Dago's presence on the liner was due to an invitation from Sard Nightbringer to participate in an auction for a groundbreaking personal shield generator. Competing against other crime lords such as Natja the Hutt, the Gotal Pari' Notgoth, and the former Imperial commander Saz Tyrson, ne Dago initially bid 10 million for the technology. After a series of counter-offers, ne Dago raised his bid to 30 million, but Natja ultimately secured the auction with a staggering bid of 100 million credits.

On the surface, Yerkys ne Dago projected an image of grace and generosity, but this was merely a facade concealing a deeply corrupt nature. He possessed a clear sense of vanity, favoring expensive attire and frequently altering the ornamental designs painted on his lekku throughout the day. Ne Dago made extensive use of his lekku when communicating, even when speaking Basic, adding a dramatic flair to his words.
