Arefu

Arefu is a small Capital Wasteland settlement consisting of four houses, located on top of a crumbling overpass bridge to the northwest of Vault 106.

The only services available here is from Mr. Ewer, who will repair items once the Blood Ties quest has been completed. And from Evan King, who will give the player various items at daily intervals (also only available once Blood Ties is completed).

Background
Arefu is a modest settlement perched atop an old freeway bridge spanning the Potomac River. The residents of Arefu destroyed the north ramp leading to Northwest Seneca Station to better protect themselves from Slavers. Arefu is the last stop on most trade caravan routes traveling from Megaton.

Arefu once had more inhabitants than it does in the year 2277, but population has decreased drastically due to the inhabitants either dying or leaving to safer settlements because of creatures, raiders, and slaver attacks. Additionally, Arefu has recently become the target of attacks from The Family, especially since Ian West went missing, and is one of the starting locations for the quest Blood Ties. 

Layout
Arefu's four houses sit atop a defensible section of the remains a bridge. Part of the overpass has collapsed, making it impossible to enter the settlement from the north. It is one of the stopping points on the trader circuit, and sandbags are also deployed near its entrance to help the inhabitants fend off attackers.

Inhabitants

 * ¹ Only if you agreed to trade blood packs for protection during Blood Ties.

Notable loot

 * Bobblehead - Repair on the downstairs table inside Evan King's house.
 * Nuka-Cola Quantum: look for a dock on the water just southeast of Arefu. Facing the dock, the Nuka-Cola Quantum is to the left on top of some poles in the water.
 * Pugilism Illustrated on a table in the Abandoned Residence, which is by the brahmin pen nearest the entrance to Arefu. This house is only accessible after negotiating protection of Arefu by The Family and informing both sides of the agreement. This book must be stolen.
 * If you follow the water that runs under Arefu to the west, you will almost immediately come to a gunboat. Although the various trunks, suitcases, and metal boxes on the stern are empty, the ones on the bow are filled with missiles. Multiple protectrons spawn in this area.

Behind the scenes

 * Just above the entrance (where the highway leaves the ground), you can see a damaged traffic sign that should read "CAREFUL," but on which the 'C' and 'L' have faded away to display "AREFU". A similar town-naming technique is used in many Wasteland settlements such as Novac in Fallout: New Vegas.
 * Arefu is a small village in Romania, most well known for its proximity to the former castle of Vlad Tepes, also known as "Dracula" and "Vlad the Impaler".
