Darth Aragnas

Darth Aragnas is a Sith Lord in the employ of the Sith Empire around 3,643 BBY. He is rivals with Nende Skye, a Jedi Master in the Jedi Order of the Republic. His most notorious crimes and activities all took place either on Curoscant or on Korriban, where he enacted various experiments.

Confrontations with Nende Skye
Their first confrontation was on Curoscant, when Master Nende Skye fought the local cartels. Darth Aragnas was brought in as an advisor to the Black Sun to produce results in the projects the Black Sun cartel had running on Curoscant. Nende Skye however prevented the timely destruction of a lower level village of stowaways, long forgotten by both the Republic as the Jedi Order.
