[[Image:TriarchSymbol.jpg|thumb|right|The symbol of the Triarch, used by all Necrons regardless of [[Dynasty]]^1-p70{{Fn|1c}}]]The '''Triarch''' was the ruling council of the [[Necrontyr]] empire before their transformation into the [[Necrons]]. Frequently undermined by rebellions in the [[Wars of Secession]], the Triarch repeatedly attempted to find ways to unify the Necrontyr race once more , be it through a common enemy such as the [[Old Ones]] or the promises of immortality made by the [[C'tan]].¹{{Fn|1d}}

The Triarch itself consisted of three [[Phaeron]]s and the rulers of individual Necrontyr [[Necron Dynasty|dynasties]] were themselves governed by the Triarch. The head of the Triarch was known as the [[Silent King]], for he addressed his subjects only through the other two Phaerons. Nominally a hereditary position, the short lifespans of the Necrontyr ensured that the title of Silent King passed from one royal dynasty to another many times.¹ {{Fn|1d}} The last Silent King of the Triarch was [[Szarekh]].^{{Fn|1a}}

Agents and protectors of the Triarch were known as [[Triarch Praetorian]]s.^{{Fn|1b}}
