Terminator armour grants the Grey Knights the ability to strike at the very heart of the enemy and endure where others would be swept away. Impervious to all but the heaviest fire, these warriors advance without faltering, their sanctified weapons reaping a terrible harvest as they go.
In a Chapter where every warrior is a psyker, the Terminators wield their gifts from within a fortress of armour, allowing them to walk through daemonic assaults that would unmake lesser souls. They are frequently the first to breach a corrupted stronghold and the last to withdraw, holding the line while the deed is done.
The sight of a Terminator Squad materialising amid a daemonic host is, for the enemies of the Chapter, a portent of ruin. Slow but utterly relentless, they embody the grim resolve of the Grey Knights, warriors who will not yield until the taint before them has been utterly extinguished.
