Geof, one of the refugees in Soltown, requested I bring him an iron blade which apparently is a specific type of sword, back to him so that he can better fight the undead. He said the easiest place to find iron blades was of slain undead in the East Perennial Trail.
Annika, the blacksmith in Soltown, offered to buy any iron ore I could bring her. I can find iron ore in the hills of the eastern Perennial Trail outside of town. Once I have it, I can sell it to her for greater than what other merchants will offer.
