Sech Turval was a Minbari of the Religious Caste who belonged to the Eighth Fane of Tredomo.[1]

In 2262, he served as an Anla'shok instructor alongside Sech Durhan. Together, they trained a new generation of Rangers from worlds as diverse as Earth, Zhabar, Pa'ri, Abba IV and even Pak'ma.[2]

Prior to Jeffrey Sinclair taking over in 2259, Turval held the position of Anla'Shok Na, (roughly translated as Ranger One) presumably since the death of Lenonn in 2247.[1]
