Breath of Silence
The Breath of Silence are sinister guild of jade-skinned Necron Deathmarks, who are among the countless small groups that serve Szarekh, the Silent King.[1]
They appear without warning, to eliminate Szarekh's enemies, and are then gone as silently as a zephyr of cosmic wind. The Silent King can never officially recognize the Breath of Silence's contribution, though, for they are dishonorable by their very nature.[1]
