— General Terminologies:
Ω Black Mire
A mysterious tower that suddenly appeared on Earth, with multiple terminals scattered across every region of the world. One sign that a person has been infected by the Mire is the occasional, haunting Murmur they hear.
Ω Floors
Within the Spire of Worms are multiple levels designed to test Espers. The theme of each level may differ; for instance, one level may focus on monster extermination while another emphasizes protection. These levels are considered conjured realities due to the altered terrain and environment. Each floor is unique.
Ω Espers
Espers are individuals who have successfully awakened and formed a connection to the Black Mire. They possess extraordinary abilities but are prone to losing control due to factors such as the emotions of others or their surroundings.
Ω Citadel
A fortress created within a floor that acts as a safe zone against monsters.
Ω Sacred Relic
A magical artifact created artificially or obtained within the tower as a reward. Only Espers can wield these weapons, and they are extremely dangerous to ordinary humans.
Ω Ascension Ritual
A necessary step that allows an Esper to evolve to the next rank. This process requires a blessed altar.
Ω Soul Slate
The core of one's soul that accumulates ether. It also functions as a recorder of one's experiences and stories.
Ω Ether
A spiritual energy that flows through the Cosmos.
Ω Ether Shard
Fragments that contain the Ether essence of a slain creature. Can be found within their bodies.
Ω Soul Color.
A parameter used to measure the quality of one's Soul Slate. There are seven colors that are ranked from lowest to highest:
• Black (Squire)
• Yellow (Knight)
• Crimson (Master)
• Grey (Saint)
• Silver (Transcendent)
• White (Angel)
• Gold (Heroic Spirit)
As an Esper grows stronger and stronger, their Soul Slate becomes more purer, allowing them to wield more power. The difference between each rank is considerably significant.
Ω Chaos Creatures
The denizens of the Black Mire. They are commonly referred to as Hollows and are ranked separately from Espers. These creatures include:
• Fiend
• Beast
• Demon
• Archdemon
• Titan
• Nightmare
• Devil
Like Espers, Hollows grow stronger as they advance through each stage. The key differences are that they possess Spirit Cores instead of Soul Slates, and the darker their Spirit Cores, the more powerful they become.
Ω Attributes
A passive ability corresponding to a person's natural traits.
Ω Mythic Ability
An enigmatic power that an Esper receives upon their awakening.
Ω Mythic Rank
A parameter used to measure the quality of an Esper's Mythic Ability. There are seven ranks, listed from lowest to highest:
• Seed
• Awakened
• Radiant
• Luminous
• Transcendent
• Holy
• Divine
Note: Possessing a higher-tier Mythic Ability doesn't automatically make someone stronger. It simply grants more versatility and potential applications. A lower-tier Mythic could, under certain circumstances, still overpower a higher-tier one.
Ω Tier
A grading system used to measure the potency of a Sacred Relic, ranging from Tier 4 to Tier 0, with Tier 0 being the most powerful and Tier 4 the weakest. Generally, the lower the grade number, the stronger the relic's abilities, but also the greater the risk posed by its inherent drawbacks. This was a fundamental flaw in the relic's system programming.
