This phrase comes for the RTS PC
Game, Starcraft. It is a phrase that is used by the Protoss race that is commonly used at the beginning and/or the end of a meeting pertaining to serious Protoss issues by members that have a high status in Protoss
society (e.g., members of the Protoss Conclave). It is a way to greet your fellow Protoss or bid them farewell.
In the original Starcraft, meetings would often begin with the phrase En Taro Adun, although the use of this phrase was not limited to meetings. Adun was a legendary figure in Protoss
history, who rid the Protoss homeworld of Aiur of the Dark Templar. Later, in the expansion set, Brood
War, the phrase En Taro Tassadar would also be employed, after Tassadar sacrificed himself to destroy the Zerg Overmind.
Most likely, the phrase En Taro roughly means "Hail," "Glory to," or "In Honor of," much
like the Nazis during WWII would greet each other with "Hail
Hitler" or "Sieg Geil" (Hail Victory). The phrase En Taro is always followed by the name of a glorious Protoss
hero that accomplished something extraordinary. The use of the phrase itself invokes
pride, courage and
hope. Sometimes when the phrase is used to end a conversation, it seems to be another way to say, "Godspeed."
