From the introduction: Every person you meet in the worlds of Dungeons & Dragons comes from somewhere. The brass-scaled shopkeep in the doorway might have two draconic birth parents, or their birth parents might be a human and a brass dragon. That surly rock gnome seems typical for her kind until she opens her mouth to speak perfect Infernal and explains she was raised in Avernus. When you ask that dwarf walking down the street if he’s born of the mountain dwarves of the western peak or the hill dwarf clan from the southern gully, he might say the truth is a bit of both. And who could forget his adorable dworc twins, one on each arm?
