Quest: The Leak That Became a Puddle
Foreman Urkrekk will be very displeased with what you have done. You let some of the witnesses slip away! Tharridon will destroy URT if he finds out what has happened here! Therefore all witnesses must be destroyed! Head into the quarry, and kill all who have seen you.

So with this great news at hand, you must make your way into the quarry. There you will find many mobs ranging from simple Excavators, to their Overseers. One such mob you will notice are the Rekk Hobgoblin Witnesses. They will be level 16-17 2dot mobs and have a randomness to their spawn points.
The suggestion would be to kill everything in the entire camp (if you can). This will up the chance that more witnesses will appear in the next respawn. You will need to kill 15 of these Witnesses and it is unlikely all 15 will be up at a time, and waiting for respawn will be something you will likely have to do.
After you slay all the witnesses, head back to Foreman Urkrekk. Although the mission didn't entirely go as planned, at least the clean-up job did. Hopefully Tharridon will never know what has happened this day.
Now head back to Trisda Sentle (who is still standing at Renton Keep) and tell her what has been done. She will offer you boots of the URT in exchange for the help that you offered.
