Deep beneath the recesses of the Garnet Mountain's Western flank is the Dwarven city of Spar. Here the powerful Hylar Mountain Dwarves have made their home-- a home that is under siege. The Dwarves are not as accepting of outsiders while things are in utter disarray, but perhaps the party can offer a hand. After all-- they likely defeated the Hill Giants at the gate. So invited in to stay at Fort Ironstone, the Dwarves fill the group in on how they can ingratiate themselves to Spar.
