Fallout 4's largest piece of DLC, Far Harbor, is just around the corner, but we still don't have all that many details about what players will discover once it arrives.

We know the DLC takes place in Maine and is based off the real-world location of Bar Harbor. We know it's the largest piece of DLC Bethesda has ever created. Beyond that, however, players are largely in the dark.

That's beginning to change now, as a few more tidbits of information have emerged, thanks to official descriptions for the expansion appearing on various digital storefronts. Here is Bethesda's official product description for the DLC:

"A new case from Valentine's Detective Agency leads you on a search for a young woman and a secret colony of synths. Travel off the coast of Maine to the mysterious island of Far Harbor, where higher levels of radiation have created a more feral world. Navigate through the growing conflict between the synths, the Children of Atom, and the local townspeople. Will you work towards bringing peace to Far Harbor, and at what cost? Far Harbor features the largest landmass for an add-on that we've ever created, filled with new faction quests, settlements, lethal creatures and dungeons. Become more powerful with new, higher-level armor and weapons. The choices are all yours."

There are a few notable pieces of information from the quote above worth highlighting, namely the various factions that will be involved. Synths and the Children of Atom both appeared in Fallout 4, but neither one was a "faction" in the sense that players could join them. The mention of "faction quests" seems to imply that players might be able to join up with either group this time around, just like players did with the Institute, Brotherhood of Steel or the Railroad in the base game. Or it could simply be new quests for existing factions.

Joining the Children of Atom certainly sounds like a fun time. The group worships nuclear bombs and radiation, with many members having developed an immunity to all the various negative effects of prolonged radiation exposure. Being able to join the cult and fully embrace their crazy ideas seems like something that is definitely within Fallout's wheelhouse. The series is known for its sometimes dark sense of humor, and joining a cult that worships the atom bomb fits the bill.

That is, of course, just speculation at this point. With Far Harbor set to arrive in May, expect to hear more official details soon.
