The story begins in Eden, where immortality reigns. Everything that anyone could ever need or want is provided for, and everyone can live an immortal life of perfect peace and harmony, with one condition: don't eat the forbidden fruit. But, one fateful day, one of the children disobeys that one rule, and the world is plunged into darkness. It is then up to the main characters to find a way to restore their Paradise.
A direct sequel, Eternal Eden: Ecclesia was announced shortly after the game's release, but soon entered Development Hell. In 2015, Blossomsoft announced that the sequel chapter would be cancelled, and the story planned for it would be incorporated into the reboot of the original title, which is currently in development.
Despite the similar name, it has nothing to do with Eden Eternal, the Taiwanese F2P MMORPG.
The game provides examples of:
- Alliterative Title: Eternal Eden.
- Brainwashed and Crazy: Downey is captured by Elvira and brainwashed to turn against the heroes.
- Cosmic Retcon: After the Final Boss is defeated, the universe is reset to the events before the conflict started.
- Crapsack World: The World of Shadows is a barren, desolate version of the World of Light. Most, if not all, of the major villains reside there.
- Death Equals Redemption: The only way to free Downey from Elvira's brainwashing is to kill him.
- Discount Lesbians: Joelle is engaged to Linette, but since fairies have No Biological Sex, they don't technically qualify as lesbians, even if they both look female and are referred to in female pronouns.
- Dude Looks Like a Lady: Jean looks so feminine that Fierro refuses to believe that he is not a girl. He is also the only guy in the party who can equip the Sexy Corset and, in fact, must wear it to lure out the Caitsith.
- Equipment Upgrade: Fierro's nun-chucks are improved by upgrading them with Bravestones.
- Forbidden Fruit: There's only one rule in Eden: do not eat the Wisdom Fruits. When this law is broken, the entire world is plunged in darkness.
- Forced Transformation: The Princess is transformed into a hideous beast after she unwittingly ate the forbidden Wisdom fruit.
- Girl on Girl Is Hot: Inverted. Downey expresses disgust when Joelle reveals her engagement to Linette.
- Happily Adopted: Fierro cares enough for his adoptive family that he's willing to trade the Orb of Courage to save his sister.
- Harmless Villain: Some monsters from the Bounty expedition qualifies -
- The Caitsith has 1 HP and dies instantly. It does have a rather... unique requirement to find, though.
- Odin only has 10 HP, and unlike the Caitsith, doesn't even have a special requirement to encounter. Even the official walkthrough states that it's no fun to fight.
- Headbutting Heroes: Downey and Jean are constantly at odds with each other due to their romantic rivalry for the Princess.
- Hidden Depths: Despite being a narcissistic, egocentric jerk, Jean is actually quite smart. For instance, when he and Downey were duelling for the Princess' favour he was the one to realize that it was a trap, and the "Princess" is actually Elvira in disguise. Downey later admits that Jean is much wiser than he is.
- Hopeless Boss Fight: The boss in the Video Game Tutorial will defeat you. It also happens to be the game's Final Boss, so it's kind of a given.
- Identity Amnesia: Josefine is afflicted with this when the party first met her. This was why she failed to recognize Elvira as her sister.
- In-Universe Game Clock: The Turtle Island has a day/night system to add the turtle hunt challenge, as certain breeds of turtle can only be found in one half of the day.
- Luke, I Am Your Father:
- Ruby, the villain who is after the second orb is revealed to be Fierro's real father.
- Josefine also discovers, after regaining her memories, that Elvira is her sister.
- Magic Music: Joelle uses music to heal, buff the party, debuff enemies, etc.
- Nice Job Breaking It, Hero: The whole conflict started when one of the protagonists decide to take the forbidden Fruit of Wisdom.
- No Biological Sex: According to Joelle, fairies are actually sexless, even though they all look female.
- Offscreen Romance: The game's epilogue shows that Fierro is engaged to Josefine, even though their interactions prior to the scene never hint at romance. The justification for this is that the epilogue takes place after a Cosmic Retcon, and the two characters would probably have a romantic build-up in this new continuity (which the protagonist, and the audience, don't get to see).
- Pinball Protagonist: Noah appears to be a mostly passive character who only got caught in the conflict because of his best friend Downey's antics. Ultimately subverted. Downey is actually a manifestation of Noah that his subconscious created to cover up his misdeeds.
- Really 700 Years Old: Pretty much everyone who live in Eden, since everyone is immortal. The story begins with the main characters celebrating their Princess' 900th birthday.
- Reality Warper: The universe in which the game takes place is apparently created by Noah to cover up the truth that he was the one who ate the Wisdom Fruit and unleashed the chaos.
- Required Party Member: ALL of them. Every single playable character is integral to the plot in some ways, and since one member always leaves/dies before the next one is introduced, you will never have an inactive party member.
- Ret-Gone: Downey does not appear in the Epilogue. Granted, being a manifestation of Noah's guilt, he doesn't technically exist, and is thus erased from the "true" reality.
- You Killed My Father: The reason why Josefine is so hell-bent to hunt down Elvira is because the latter killed the former's master.
