Tyver Salast was an admiral in the Galactic Navy and the Ranquell Peace Commission in the waning days of the Galactic Federation of Free Alliances. He was a brash, compulsive veteran commander, and was directly responsible for the bombardment of Mortis and the resulting Shadow Crisis in 296 ABY.

After leading an unauthorized military strike force and engaging both the Jedi Exiles and Old Order fleets in a fight to a standstill over Mortis, the admiral refused direct orders from the Chancellor's Office and proceeded with a planetary assault of the force-world. He, along with most everyone else present, died instantly when the planet was destroyed.
