Some people are just born lucky- for Clan Grutnik, this couldn't be more bluntly stated. Situated on a mountain overflowing with warpstone- the most valued mineral of the Skaven world -this clan has made a killing offering exclusive supplying treaties with both Clan Moulder and Clan Skryre, earning warbeasts and weapons aplenty. Likewise, they trade with other local Warlord clans- slaves are always in demand (warpstone is dangerous to mine, since it causes death and other unpleasant things to happen).
Unfortunately, warpstone has become more then just a commodity- it's also become a part of their lives in a much more literal sense! Weapons, armor, various lucky trinkets- even the slaves are branded with warpstone. Naturally, the obsession is a concerning one.
