Recently, just before the troggs surfaced within the site, we had uncovered a large number of strange, carved idols. But we didn't have the chance to study them, for soon after their discovery the troggs chased us away from the ruins! And those idols have a strange effect on the yroggs. It makes them go berserk!
Bring me 8 idols - I want to study them, and I want them out of trogg hands! You can find the idols on the troggs infesting the site.
