Ratkin Slaves
Rats are everywhere. Rats are vicious, hard creatures that can survive in the harshest of conditions, living in filth and eating worse. They thrive in adversity. The darkest, most miserable places in the world are the domain of rats. If ever a race was destined for slavery, ideally suited for the despair and brutal life it offered, it was the vermin.
And so Bharzak cloistered himself away in his laboratory, and toiled for almost 13 years, experimenting on stricken slaves, and vermin infused with the power of the Abyss. At last, a new race was born, the Gnorr, or ‘Ratkin’. A subservient slave-race, with a propensity to multiply rapidly, they seemed the answer to
Bharzak’s prayers. And yet they would eventually prove his greatest failure.
Unseen by their masters, the Ratkin tunnelled into the very chasm of the Abyss, undermining the vast cellars and sewers of the twin cities, and eventually escaping Tragar completely.
