The Ultimate leader of the
Rangers, called "
Ranger One" by the humans.
In accordance with the laws of the Israelites, the two roles of Leader and General were separated to allow a balance of power and to prevent a tyranny, President Sheridan decided that the President of the Interstellar Alliance could not also hold the roll of Entil'Zha, since the Rangers were the military arm of the Interstellar Alliance.
The role was created by Valen, who was the first Entil'Zha when he formed the Rangers in the year 1250. For 900 years, no other Ranger has held the rank.
Title given to Jeffrey Sinclair when he took up the struggle for preparations for the Shadow War, on Minbar. At the request of the leader of the Grey Council
Sinclair was the first human, and the first individual, to to inherit the Minbari Rank of Valen.
Chronology of the Entil'Zha rank
1250 - 1350 - Valen
1350 - 2258 - Rank is unoccupied in respect for Valen
2258 - 2260 - Jeffrey Sinclair - (cf. "To Dream in the City of Sorrows")
