As life was viewed cheaply, the world had one too many martyrs. Those who would have gladly and practically sold themselves to the rich and powerful for little more than a single meal were abundant. They gladly did so in the name of courage, fairness, or some such other thing.
An assassin need not be a martyr, but martyrs could definitely be assassins. They did not operate under bright daylight, their notion of fairness had nothing to do at all with the principle of Equivalent Exchange held by all mages.
Martyrs who went about fulfilling their missions in the battlefield, did so for victory and glory.
Cuisi looked up and the word 'martyr' crossed his mind. There were no martyrs among demons. What demons wanted more than anything was to live for as long as they could manage. They yearned to live, even if it meant living a life filled with humiliation and suffering.
