Dessicus served as the head of the GenoHaradan group situated on Nar Shaddaa.
Meetra Surik sought him out, aiming to eliminate the bounty placed on herself and her allies. Dessicus, having analyzed her fighting style, felt assured of his victory over her. Nevertheless, he was defeated and sustained fatal wounds. As his life ebbed away, the organization's base activated a self-destruction sequence, and Surik barely managed to escape with her life. The resulting blast erased all traces of the GenoHaradan's presence on the world, adhering to their strict confidentiality protocols.
Originally, Dessicus's location was planned to be the subterranean fortress below Jekk'Jekk Tarr. Following the citadel's destruction, Zez-Kai Ell was intended to rescue Surik from certain death by fire, although her companions, including Darth Sion, would briefly presume her demise. The removal of the GenoHaradan from Star Wars: Knights of the Old Republic II: The Sith Lords, likely due to scheduling issues, led to Visquis being assigned to the underground lair instead.
The The Sith Lords Restoration Project aimed to reinstate the GenoHaradan, including Dessicus, at a significantly later point in the game compared to the initial design. This project was ultimately discontinued, but the GenoHaradan has since been reintroduced through an independent modification.
