Glowing Sea

The Glowing Sea is a location, or more accurately, a map area containing several locations in the Commonwealth in Fallout 4.

Background
Originally the ground zero of a nuclear detonation during the Great War, the Glowing Sea is now a dangerously irradiated hotzone with an above-average exposure of radiation. Storm systems that pass over the Glowing Sea become irradiated and spread radiation into other parts of the Commonwealth wasteland.

At the center of the Glowing Sea is a settlement known as the Crater of Atom, inhabited by humans from the Church of the Children of Atom. Southwest of the Glowing Sea, outside the boundaries of the map, is also the Rocky Cave, inhabited by Virgil.

The Glowing Sea, despite its name, is not actually a sea; rather, it is essentially a totally annihilated area of southern Boston (supposedly the area of Milton or Dedham, both areas south of Boston proper), home to very few buildings and a couple of generally intact structures, though most of them are either underground or largely inaccessible. There are also portions of the ground that are entirely composed of trashed metal, concrete, and other materials, suggesting that the area of the Glowing Sea contained more structures before the war. However, much of the Glowing Sea consists of barren dirt and yellow, glowing pools of irradiated waste.

Layout
The Glowing Sea is a heavily irradiated area, normally causing 10+ Rads a second (60+ in the liquid sections). A suit of power armor or RadAway and even Rad-X needs to be brought to stay alive. A hazmat suit can also be used, but will not protect against enemy attacks. The layout of the area is mostly just a wasteland filled with deathclaw, radscorpion, large packs of feral ghouls, Mole rats and the somewhat rare bloatflies, bloodbugs or stingwings.

Locations

 * Abandoned shack NW of the Atlantic Offices almost on the western map border
 * Atlantic Offices NE of the Crater of Atom NW of the Capsized factory
 * Capsized factory NE of the Crater of Atom SE of the Atlantic Offices
 * Caves - two small, unremarkable caves underneath a road near a Red Rocket station. This cave is south-west of the Vertibird wreckage.
 * Crater of Atom Just to the SE of SW corner of map, housing the Children of Atom
 * Decayed reactor site in the western end beyond the map, NW of the Decrepit factory
 * Decrepit factory At the SW corner of the Map
 * Federal supply cache 84NE NW of Cave 2 squares away from the western border line
 * Forgotten church West of the Abandoned shack.
 * Hopesmarch Pentecostal Church N of the Vertibird wreckage.
 * O'Neill family manufacturing SE of the Crater of Atom past the edge of the map.
 * Jack Frogson's sausage factory on the NE corner near the hill.
 * Relay Tower 0DB-521 NE of Skylanes Flight 1665 below edge of map
 * Rocky Cave In the SW end past the edge of the map
 * Sentinel site SE of the Crater of Atom, directly south of O'Neill family manufacturing past the edge of the map
 * Skylanes Flight 1665 NE of O'Neill family manufacturing and Sentinel site; SW of Relay Tower 0DB-521
 * Vertibird wreckage W of Relay Tower 0DB-521
 * In the SW end, near the decrepit factory, is an area which could be considered the "Center" of the Glowing Sea as it is ground zero of a nuclear strike, and more than likely the reason for the Sea existing.
 * Parking garage, an unmarked location just north of the southern Cave, beneath a destroyed Super-Duper Mart.
 * Red Rocket, an unmarked location just northwest of the most northern cave.

Notable loot

 * Level-generated set(s) of Power armor.
 * Gamma gun
