Spoiler Warning:Plot details follow. Read at your own risk.
The dreaded Heavenbringer is the Titan spoken of in the lore for Etrian Odyssey IV: Legends of the Titan, and is the final boss of the same game. Thankfully for the Explorers, the Medium is able to keep it from unleashing its full power, but she won't last long. In order to save her, and the world, you'll have to slay this god.
Long before the events of the main story, most of the land was wiped out by an unknown cataclysm. The cataclysm not only destroyed a large part of the human race, but also poisoned the land and made it unsuitable for human life; however, life still existed (suggesting against nuclear Armageddon). The remaining humans then opted for what would be called the Yggdrasil Project. Instead of struggling to adapt to their new world, they chose to adapt the world to them. In order to facilitate their research, they created the three Servitor Races: Vessels, Sentinels, and Hollows. In order to avoid depleting what few resources humans could still use, the Servitors were created with the ability to survive the new landscape. Eventually, the Project was completed, and the Yggdrasil tree was planted. The land would later be purified by the tree, as the tree would absorb all toxins and miasma from the world. However, the plan was not perfect. The tree could go "berserk," and unleash the toxins back into the world; worse yet, it could unleash a disease that could cause plants to grow from within the body until your eventual death. A countermeasure to this was attempted, but the program failed disastrously. After eons, the tree eventually did go berserk, becoming a mighty humanoid Titan, and the Imperials fled from the resulting Titan. Many humans teamed up with the Servitor races to defeat the Titan and separate its three symbols of immortality (Heart, Soul, and Crown). As a result, the Titan returned to its tree form, and the land was purified.
Now, many years later, the player inadvertently allows the Imperials to put the three pieces of the Titan together once again, allowing the tree to go berserk and revert to its godlike humanoid form. The only ones who can possibly stop it now are the brave explorers who set everything in motion in the first place.

Bared Essence
Description
Yggdrasil's head, become the Titan. Even asleep, the Medium barely keeps the Titan's power at bay.
Unlike the final bosses in other games, you may re-fight the Heavenbringer if you talk to the Medium in the Misty Ravine and choose to stay by her, starting from 14 days after the Heavenbringer's defeat. This fight can be attempted again after another 14 days, and is needed to obtain materials to forge the Durandal.
Trivia[]
Most people believe the Bared Essence is the result of breaking the Heavenbringer's face, but in reality it is only opening its mouth at an impossibly grotesque angle. This can be easily confirmed simply by rotating the monsters image in the Monstrous Codex while in game.
The Medium can be seen stuck above the "eye" of the Bared Essence.
