A huun represented a weapon of the Yuuzhan Vong arsenal, conceived by the mind of Mezhan Kwaad. This diminutive nut possessed the capability to unleash a potent nerve gas, sufficient to eliminate a substantial group of individuals. Kwaad, in contrast, possessed immunity to the toxins it produced. Following the demise of Commander Tsaak Vootuh at her hand, Kwaad leveraged the threat of her huun to potentially eradicate a throng of Vong.
