The Dwarves of Spar, led by Bonumli, have been having issues with the Hill Giants for some time. They're far more organized than they have ever been, showing increased tactics and working as more than a singular unit. This is not something Hill Giant level intelligence typically yields. However-- if there was something higher in the Ordning, it was possible that they could have organized the giants. While the Dwarves were aware of a camp of Hill Giants, efforts to figure out what laid inside have been difficult. None of the parties sent have returned, but if a group of adventurers made their way to help...
Unsurprisingly the camp is massive, carved into the sides of the mountains with trees felled to create the massive barricades. This is far more craftsmanship than a creature that lacks intelligence to yield. What's worse-- they seem to have taken up animal husbandry, raising nightmarish looking beasts.
