## Plot

### Setting and characters

The Dragon King's Tower, Yggdran, once housed Seven Hidden Treasures that could bring peace. But one day, the Seven Devil Kings stole the treasures and used their powers to turn Yggdran into a terrible dungeon. You have been guided to Tir na Balc, the land of the fairies. Chosen by the Queen of the Fairies, Eternia, to defeat the Seven Devil Kings and retrieve the Hidden Treasure Clanniebe. The Queen grants you her blessing using Secret Revival Magic, allowing you the ability to resurrect endlessly as you explore the depths of Yggdran.

### Story

#### History

Long ago, the primal God separated into 3 forms: the God of Light, the God of Dark, and the Dragon King. While Light and Dark were in constant conflict, the Dragon King attempted to maintain a balance between the two forces. The God of Dark, represented by demons, had the upperhand. The humans, who represented the God of Light, were weak. To solve this imbalance, the Dragon King allowed the God of Light to grant men the power of the Cavalier.

The Dragon King created the land of the fairies, Tir na Balc, as a place for defeated Kings and Gods to rest and regain their power. He erected a colossal tower called Yggdran where he left Hidden Treasures that could keep the peace in the land, and he left powerful Guardians to watch over them.

When the Dragon King left, he ordered the fairies to protect the treasures and to pass on The Fairy Poem.

#### Before Mon-yu

Some time before Mon-yu began, the Great Devil King Aldin was defeated in another world and appeared in Tir na Balc. He was able to possess Eternia, and concocted a plan to restore his powers using the Seven Hidden Treasures. He used Eternia's unique position to trick Heroes from other worlds to collect the hidden treasures for him.

At some point, Eternia's most trusted follower and strongest Hero, Sieg, received a message from the God of Light informing him of Aldin's influence on Eternia. The God of Light granted Sieg the 8th Hidden Treasure, Einherjar, which granted him immortality and immunity to Aldin's power of Charm. Unfortunately, because Sieg was not chosen by the treasures, the power of Einherjar slowly drove him mad. He wandered the Dragon King's Tower with the only goal of protecting the Seven Hidden Treasures from would-be Heroes sent by Eternia to collect them.

#### Mon-yu

You are a Hero who has been summoned to Tir na Balc by the Queen of the Fairies, Eternia. Eternia tells you about the Seven Hidden Treasures, relics of great magical power that contain the life force of all Fairies. Long ago, the Seven Devil Kings stole the treasures for themselves, putting the Fairies and Tir na Balc itself in grave danger.

While the Heroes are on their quest, a man named Holy Knight Sieg appears and tries to stop the Heroes from defeating the Devil Kings. Eternia tells the heroes that Holy Knight Sieg was once her most trusted Hero, but he was charmed by Darkness and betrayed her. After defeating Sieg multiple times, Eternia wonders how he is able to revive himself without Eternia's Secret Revival Magic. Eventually, she gives the heroes a dagger that she says should be able to stop him from reviving endlessly. When Chuck hears of this plan, he gives the Heroes the Light Deity Statue, a statue that once belonged to Sieg, and asks them to use it to attempt to restore his sanity.

The next time you defeat Sieg, you can choose to use the dagger or the Light Deity Statue. If you use the Light Deity Statue, Sieg will come to his senses and tell you the truth of what happened. Long ago, the God of Light spoke to him and told him that the Devil Kings are not evil, but actually the chosen guardians of the Hidden Treasures. Eternia has been possessed by the True Devil King, Aldin, and is using the Heroes who come to Tir na Balc to collect the treasures in order to restore Aldin's power.

The God of Light also gives Sieg the 8th Hidden Treasure, Einherjar, which gives him immunity to Aldin's charm. Unfortunately, because the treasure did not choose Sieg, it drives him insane.

By the time the heroes learn this, Eternia has already collected all 7 Hidden Treasures. When the Heroes return to Einheim to confront her, she has already gone to the top of Yggdran to perform the ritual to restore Aldin's power. When you arrive at the Dragon's Jaw, she attempts to offer you half of Tir na Balc in exchange for becoming her minion. When you decline, Eternia uses the treasures to restore Aldin, and you begin the final battle with the True Devil King.

After defeating Aldin, Sieg uses the Long-Near Crystal to ask you to use Einherjar as a last-ditch effort to revive Eternia, whose body was sacrificed to summon Aldin. Eternia is revived, and the Heroes forgive her for what she has done. In response, Eternia writes a poem to eternalize the Heroes.

## Gameplay

Most of the gameplay elements build on the systems found in Undernauts: Labyrinth of Yomi, offering almost the exact same character creation system with the same classes and even the same skills and spells.

### Playstyle

The game comes with 3 difficulty settings called "playstyles". The playstyles don't change the overall gameplay, but they do limit your access to useful features (maps), and they limit the maximum level of your characters during different sections of the game. If you're struggling on a harder difficulty, you can lower the difficulty freely, but you cannot raise it.

### Creating your Heroes

Character creation has been significantly simplified from even Undernauts: Labyrinth of Yomi, getting rid of backgrounds entirely. The only fundamental distinction between characters are their jobs and stat rolls. Jobs determine your attributes and your skills. There are eight jobs to choose from: Knight, Fighter, Samurai, Warrior, Gunslinger, Mage, Ninja, and Cleric.

### Upgrading Your Heroes

When your hero gains enough experience to level up, you can freely level up at any time. When leveling up, you can choose to place a point into any attribute you wish. You have a hard limit and a soft limit on your hero's maximum level. The hard limit is the actual level cap that is enforced by your playstyle and the section of the game you are in. There is a soft limit, where you receive better rewards for having a lower average level during your Hero Evaluation.

#### Upgrading Equipment

Unlike Undernauts, money is not used to upgrade equipment. Instead, while you gain experience from defeating enemies, your equipment is also gaining experience. This means that even though you can't level up your characters beyond a certain point (due to the level caps), you can still strengthen your character through their equipment.

#### Skill Points

Also unlike Undernauts, you do not gain skill points by leveling up. You gain skill points independently from your level, giving you yet another progression system that bypasses the level cap.

### Evaluations

After being sent by Eternia to defeat a Devil King, you will be evaluated on your performance in the boss fight and given a letter grade from D to S. There are three primary evaluation points: the average level of your party, the number of turns it took you to defeat them, and the completeness of the dungeon map. Depending on your last evaluation grade, you will receive a buff that upgrades future loot chest ratings, as well as potentially bonus items.

* B rank chests will become A rank.
* C rank chests will become B rank.
* C rank chests will become B rank.
 B | ⭐ x8 | * C rank chests will become B rank.

### Annihilation

Once all of your heroes are downed in combat, your team will be revived by Eternia's Secret Revival Magic. You will receive 2 blessings after being revived: HP/MP Boost and Experience Conversion. Your Heroes will receive a small permanent increase to their health and mana, and experience gained beyond the level cap will be converted into gold.

### Collecting Treasures

Upon defeating a Devil King, you will reclaim a piece of the Hidden Treasure. This will increase your character's level cap, grant access to new features, and unlock the next stage of Yggdran.
