During the time when Agarthan civilization prospered, the hubris of humanity fueled its citizens to turn them against their benefactor, the progenitor god herself. The war that ensued caused the majority of that civilization to collapse and left the land devastated. Some of the survivors retreated beneath the ground during that time.

Waiting for their chance at revenge, their descendants, Those Who Slither in the Dark, stole the blood and hearts of the progenitor god and her children, and created Crest stones. Over a thousand years later, that revenge neared its fruition.

History

"Just a minute! The following section contains spoilers. Viewing it will cost a lot. Are you prepared to pay for it?"

In the Black Eagles route, though Edelgard joins forces with them, she makes it clear that she has every intention of defeating them if they continue to be a threat. After reuniting Fódlan under the rule of the Adrestian Empire, Those Who Slither in the Dark remain at large, Edelgard devotes herself to hunting them down during her reign.

In the Church of Seiros route, after Edelgard and the Adrestian Empire are defeated, Rhea and Byleth receive a posthumous message from Hubert, who explains the need to destroy Those Who Slither in the Dark and provides a map to their underground stronghold, Shambhala. There, the forces of the Church confront and defeat Thales, who then attempts to kill everyone with him by activating powerful Agarthan weapons to destroy Shambhala. Rhea destroys many of the weapons and is wounded in the process, but survives.

In the Blue Lions route, though Dimitri suspects a conspiracy was behind the massacre at Duscur, he never learns their role in it. Edelgard allies with Those Who Slither in the Dark to bolster her forces as the Holy Kingdom of Faerghus advance on the Adrestian capital of Enbarr.

In the Golden Deer route, Those Who Slither in the Dark succeed in their grand plan and revive the King of Liberation, Nemesis, and his army, who they wish to destroy the Church of Seiros and all of the people of Fódlan. Claude and Byleth manage to defeat Nemesis before he can begin his reign of terror.
