Tharn (mirror)

Leader of the Halkan council in the Mirror universe who refused to supply the Terran Empire with dilithium crystals, even though to do so would be to face annihilation as a race. Spock (mirror) got the Halkans to yield by convincing them that they could serve as a role model for his reforms. Their pacifist views found a widespread following in Spock's new government, but it lead to Spock's being overthrown by the Imperial Starfleet (A Debt of Honor). They were subsequently annihilated as a race, but Tharn did not live to see this, having died from natural causes shortly before this ("The Ones with a Vision").
