Darth Caldoth

Darth Caldoth was a Force-sensitive Duros male Dark Lord of the Sith. At one point, Darth Caldoth wrote a book titled The Bestiary of Darth Caldoth, which mentioned various Sith warbeasts such as the veergundark.

Darth Caldoth eventually gained a Sith apprentice, the Twi'lek Ry Nymbis. At one point he used his own lightsaber when he traveled to Simoth and when reunited with his apprentice Ry Nymbis Caldoth killed his own apprentice with a Sith ritual that turned the young Twi'lek's body into stone.

There was a legend about Caldoth coming into conflict with the Nightsisters of Dathomir after stealing a pod of a buried Nightsister. The coven member Zeldin was chosen to practice magick in order to seek revenge against Darth Caldoth. Zeldin reached out telepathically to influence the Sith Lord, however, Darth Caldoth was aware of her presence, and trapped Zeldin in a cage in his own mind.
