In this world, energy is everything—it flows through the land, the sky, and all living beings. Mortals and Demi-Kings alike draw power from Vis Mundana (World Energy), but their paths to strength differ greatly.
Mortals have a store of energy inside them called Virtus Mortalis ,along with the Vis Mundana thats inside of them, an adaptive and evolving power where individuals resonate uniquely with the environment.
Imagine the Virtus Mortalis as an enzyme inside of you. Whilst the Vis Mundana in the atmosphere is the substrate. A mortal will pull in the Vis Mundana and it will interact with the Virtus Mortalis inside a mortal, like an enzyme reacting with a substrate.
Then the product would be the ability of the mortal such as the ability to wield fire etc... Since every mortal has different forms of Virtus Mortalis the product will always be different even if they all use the same Vis Mundana.
However Virtus Mortalis needs energy so mortals have to feed it a different form of Vis Mundana which a mortals body will naturally process inside of them by absorbing the atmospheric Vis Mundana over slow periods of time. This is the energy which powers Virtus Mortalis to interact with Vis Mundana as a catalyst
Mortals refine their strength through personal mastery of Vis Mundana. Their growth follows three fundamental aspects, each with seven mastery stages:
Imperium (Control) – Mastery over Vis Mundana Manipulation
Inceptio (Initiate) – Basic energy manipulation, unstable abilities.
Disciplina (Disciplined) – Gains fundamental control.
Dominium (Command) – Energy responds efficiently.
Harmonia (Harmony) – Perfect synchronization with the environment.
Praestantia (Excellence) – Energy moves instinctively.
Regnum (Sovereignty) – Can control multiple forms of energy at once.
Absolutum (Absolute) – ???
Quantitas (Quantity) – The Total Vis Mundana stores in the body
Gutta (Drop) – Minimal energy reserves.
Rivus (Stream) – Slightly improved stamina.
Flumen (River) – Moderately sustainable energy reserves.
Mare (Sea) – Can wield energy for extended periods.
Tempestas (Storm) – Near-boundless energy, requiring strong control.
Abyssus (Abyss) – Feels endless, but reckless overuse leads to collapse.
Infinitum (Infinite) – ???
Qualitas (Quality) – The quality of the Vis Mundana inside the body
Crassus (Crude) – Energy is inefficient and wasteful.
Modicus (Moderate) – Energy use stabilizes.
Efficiens (Efficient) – Minimal energy loss.
Acutus (Sharp) – Highly refined techniques.
Puritas (Pure) – Perfect control over energy's form.
Divinus (Divine) – Energy transcends normal constraints.
Veritas (True) – ???
Mortal Tiering System
A mortal's overall strength is determined by the culmination of their three fundamental aspects (Imperium, Quantitas, Qualitas). The combination of all three defines their tier:
I – Initiatus (The Initiated)-Novice-Has just begun their journey, barely capable of manipulating Vis Mundana.
II – Progressor -(The Practitioner)-Beginner-Has developed moderate control over one or two fundamental aspects.
III – Adeptus (The Adept)-Intermediate-A balanced wielder of Vis Mundana, possessing notable skill but not yet refined.
IV – Dominus (The Master) -Advanced- Has reached high mastery in at least two aspects, beginning to show immense power.
V – Magister -(The Grandmaster)-Expert-A rare mortal, capable of shaping the world through refined energy manipulation.
VI – Transcendense- (The Transcendent)-Peak Mortal-At the edge of Pure Transformation, only a step away from becoming a Pure Being.
VII – Pura Essentia -(The Pure Essence)-Pure Being-Has surpassed mortality, wielding strength akin to newly ascended Kings.
Final Stage: A mortal who reaches the peak of all three aspects undergoes Pure Transformation, becoming a Pure Being. However that's not the end of their journey...
