I try to avoid them if I can. I see them sometimes herding their flocks of flabby grey creatures into and out of Boston harbor, and it always gives me the chills. Briano tells me that they brought me back to life, but I can't remember it. I can't remember a lot of stuff. He also tells me that I was good friends with one of them once. One of the ones that begs outside of Grand Island Bank for nickels or blood. I can't tell you why I'm uncomfortable around them. They're just fish.
In the days of old, before the dominance of humanity, the giants were the supreme rulers of the world and their crafts were considered to be the best. These beings venerated the god of the forge above all others and their swords and armors were the best that could be had even in the days of their decline. A hero seeking a masterwork sword might have to voyage long and hard to find a surviving giant smith or cache of rare and valuable giantcraft weapons.
