"Oh no, not monsters," just as William expected, the old merchant waved his arm, denying this hypothesis, "there is… Something much scarier lives here. We don't know what it is. But people used to say these are the vengeful spirits of the old residents of this city before its demise."
"Vengeful spirits? For real?!" William didn't buy any of this.
"No one ever saw these creatures and lived to tell the tale. What we know is that they are drawn by any sound, and we learnt such a lesson after lots of bitter losses."
"Drawn by sound?" William paused, lost in thoughts for a few moments before dropping such an idea. Trying to guess the identity of these mysterious creatures just from this useless intel was impossible.
"That's not important now," the old merchant grinned, "see this? This is the block which belongs to our group. Isn't it amazing?"
