Bask Sunn was a Dar'manda lieutenant, recruitment officer and a former Mandalorian, who represented the Dar'manda in Heta Kol's organization known as the Hidden Chain during the third Galactic War between the Galactic Republic and the Sith Empire, around 3626 BBY. Sunn was a Mandalorian Combat Master.
In 3626 BBY, Bask Sunn lead a group of Dar'manda to attack the Spirit of Vengeance II alongside Clan Varad and the Ash'ad at the behest of Heta Kol. He was confronted by the Alliance Commander and Rass Ordo, who bested him in combat. He pleaded for his life by giving the Commander and Rass a set of codes and a personal transport that would enable them to carry on destroying the tethers that were latched to the Spirit of Vengeance II, and was subsequently spared by Rass. He later reported to Heta Kol following their retreat from the ship, who gave him new orders. He then also sent a message asking the Commander for his transport back, since it was part of a matching set.
Bask Sunn on Ruhnuk
Bask was later present in the Hidden Chain meeting when Ri'kan Kateen reunited with the group and brought his sister, the rogue Jedi Padawan Sa'har Kateen, to Heta Kol.
Bask Sunn would ultimately lose his life following the Showdown on Ruhnuk.
During the duel between Heta Kol and Shae Vizla, the player takes notice of Bask Sunn using a weapon to hinder Shae Vizla, without Heta's knowledge, so that Bask can gain a huge profit over Shae's defeat and he gives the player three options on how to proceed regarding the duel:
- - Shae Vizla overpowers and defeats Heta Kol in front of the Hidden Chain. Bask will then attempt to hurt the player to which the player can either knock him out or kill him.
- - The Commander knocks Bask Sun and then points the sonic disruptor on Heta who is suddenly unable to move freely, and Shae manages to defeat her, but the Hidden Chain does not acknowledge the victory and neither does Shae. Bask will then attempt to hurt the player to which the player can either knock him out or kill him.
- - Shae will lose the fight and Bask Sunn promises to have Dar'manda not only leave the Hidden Chain but also support the player's faction in the war. Saboteurs have the modified option where they leave the machine but tell Bask Sunn to support the opposing faction (Republic for Imperial saboteurs and Empire for Republic saboteurs) instead to his confusion to which he agrees to regardless.
In the following Update 7.3: Old Wounds, if the player had chosen to destroy Sunn's weapon or used it on Heta, Heta will figure out his interference in her duel against Shae. If the player had spared Sunn, Heta will have him flushed out the airlock. If the player had taken Sunn's deal, Heta will be unaware of his treachery and assumed he had pulled Dar'manda out of the Hidden Chain once he received his payment.
