" This is not to say that aggression belongs only to those who are attackers,’ Silchas resumed. ‘Far from it, in fact. In my talent with the sword, for example, I am for the most part a defender. I rely upon timing and counter-attack – I take advantage of the attacker’s forward predilections, the singularity of their intent. Counter-attack is, of course, aggression in its own way. Do you see the distinction?’ Ryadd nodded. ‘I think so.’ ‘Aggression takes many forms. Active, passive, direct, indirect. Sudden as a blow, or sustained as a siege of will. Often, it refuses to stand still, but launches upon you from all possible sides. If one tactic fails, another is tried, and so on. "
