For the definition of this name, see Salla (title).

The Salla (who was named Vlagro) was a religious figure in the Nasgulian culture of the 23rd century. Vlagro took the title of Salla controversially, succeeding a Salla named Watan. Vlagro's sister was named Ravia. (DC TOS comics)

The Federation learned of the predicament and conducted a secret intelligence program against the new Salla and his oppressive government, officially recognizing Watan as the true Salla. A secret agent, Dav, was placed in the Salla's midst. Dav's primary role in the Salla's service was to shout slogans such as "Hail, Salla" whenever the Salla spoke. (TOS comic: "Target: Mudd")

The Salla viciously destroyed many enemies, including dissidents such as Argus. In the late 2280s, Argus fled from Nasgul space and sent a message requesting protection from the Salla. Nasgul military starships chased Argus's small vessel and severely damaged it, although Argus's call was answered. He was beamed aboard the USS Enterprise-A, where Captain James Kirk granted him asylum. (TOS comic: "The Return!")

The Nasgul vessels carrying the Salla arrived and hailed the Enterprise. The Salla was infuriated at Kirk's interference. Argus begged the Enterprise crew to turn off the viewscreen, and Salla pronounced Argus's death sentence. Argus died immediately, even though Doctor Leonard McCoy could find no energy transmission, technology, chemical, or biological weapon that could possibly have caused Argus to die through the mechanism of a few words spoken by Salla.
