The Broodmother

As is often the case with infestations such as the one we are facing at Gloomrise, a single powerful matriarch often leads to the rapid spread of a hostile spider population.

If we wish to drive these beasts off for good, we'll need to seek out the progenitor and end her. When you go to Gloomrise, seek out the broodmother there and destroy her. I'd advise you to bring allies, and be ready for anything. These seem to be no ordinary spiders.
