Glowing Sea

The Glowing Sea is a region within the Commonwealth, just south of Natick.

Background
The Glowing Sea is the most highly irradiated region in the entire Commonwealth. It was ground zero for the high-yield nuclear blast that devastated most of Massachusetts, centered around the Crater of Atom, as it became known to the mutated humans living there. Covered in a toxic fog and heavily irradiated, the Glowing Sea is a desolate place where only the hardiest lifeforms might survive. Deathclaws, feral ghouls, and many more monstrosities lurk within this storm-wracked stretch of the wasteland. While short stints on the edges of the Sea might be survivable with the right chems, heading towards the interior requires power armor or other highly protective gear such as the hazmat suit.

The region is a great unknown, as the Glowing Sea is so heavily irradiated that it's impossible to scan remotely, due to echoed readings and false positives. The fact that it's heavily irradiated and inhabited by some of the worst of Commonwealth monstrosities certainly does not help. If someone should get lost inside, help is not coming, as the elevated radiation levels generate so much interference it takes a dedicated distress pulser to have any chance of successfully reaching an outside recipient - and even then, only if they are near the Glowing Sea.

The Commonwealth itself is occasionally plagued by radstorms that blow in from the Glowing Sea.

Appearances
The Glowing Sea appears only in Fallout 4.
