The Creature of the Wolfsktaag is a metallic (robotic) giant spider whose lair is in the Wolfsktaag Mountains.
It attacked Shea Ohmsford nearly killing him, but his party wounded its eye causing it to flee, bleeding cerosene.
20 years later, it was polluting the stream that fed the Blue Pond. As it was essential for the Healer Gnomes of Storlock (and saving the life of their friend, Davio), Jak Ohmsford's party traced the source of the pollution to the wounded creature. Shella Leah fired a flaming arrow to its good eye, blinding it. Telsek then, using the power of the Black Irix, climbed and pushed a rock that crushed it. Then the party did their best to clear the pollution off the stream.
