5. Like Novac of Fallout: New Vegas and The Pitt, Arefu of Fallout 3 gets its name from a nearby sign that has fallen into disrepair, in this case the letters “C” and “L” obscured from the word “CAREFUL”. Coincidentally, Arefu is also the name of a Romanian village known for its proximity to the castle of Vlad III, the inspiration for Dracula. Meanwhile Arefu is plagued by constant attacks from local vampires, who you can find in Meresti Metro Station, another location named for a commune in Romania.
