Balton asked his soldiers to lay traps. He thought that he would soon catch the beast that visited the den.
The soldiers obeyed him and laid many nets near and inside the den. Of course, those were no normal nets.
They had special magic imbued in them. They would zap or give a paralytic shock to the beasts or monsters that would touch them. Needless to say, humans would also get shocked, therefore it was necessary to handle them with care.
That was why a special glove-like apparatus was given to hold the net without any problem. Those very gloves ensured that no one got paralyzed because of their own net.
The soldiers did exactly as they were ordered and placed the nets. They themselves then hid near the cave. Some of them hid in the trees while others kept watching from a bit far away place.
Of course, they had binoculars like instruments that enabled them to look into a farther place.
Now all they had to do was wait for the beast to arrive.
