I have no love for the sea, nor any creature I've seen come from its depths. It is a powerful but blind mistress; callous and brutal. It would bring me great pleasure to slay the fish men by the hundreds if it were within my power. But I garner some pleasure from watching their deaths at the hands of any who do the Horde's will.
Which brings us to you, <class>. How many can you slay? Would you test yourself against their most powerful kind?
The sea seems vast and relentless, but you have stained her with the blood of her own spawn. The fish men know pain. Their stupidity will force them to refortify their ranks from the devastation you've caused, and that is good.
Let their gurgling screams overshadow the sea's roar long into the night. I shall smile every time I hear one of them silenced.
Return to me if you wish to slay more of the fish men. I will gladly reward you again.
