Hastur

Admiral Hastur was a Starfleet officer from the 24th century.

Hastur commanded the relief force from the bridge of the USS sent to reinforce Deep Space 9 after the Klingon invasion of the Cardassian Union. 

Hastur then was placed in command of Starfleet operations in assisting the Union. He was in charge of the first Federation convoy sent with aid to the Cardassians. (: "The Darkness Within")

By mid-2373 Hastur was no longer in command of the USS Venture. (: "Vengeance")


 * In Star Trek: Swiftfire, Hastur is described as an aged male human. This is pure speculation as Hastur's species, gender and age were never mentioned on screen.
