Prospective Initiate Briefing Document
Issued by Authorized Scouts of the Ossirian Deep
If you are reading this, it means one of our scouts has identified measurable resonance within you.
That resonance is not imagination.
It is not coincidence.
It is measurable.
You possess a Mana Core.
Most people do not.
Ossirian Deep Academy is the last surviving Grand Academy of the Arcane Accord. It exists beneath the Ossirian Sea, housed within the Auric Dome at abyssal depth. It has endured wars, purges, bloodline collapses, and the slow erosion of magical knowledge across the surface world.
We do not recruit casually.
We do not recruit often.
You were measured for a reason.
Every mana-born individual develops a Mana Core during early adolescence. This core anchors you to one of the Six Mana Lines:
Fire
Water
Wood
Earth
Metal
Ambient
You do not choose your line. It is fixed at formation.
Your capacity to wield that line is measured by the Mana Purity Index (MPI), a 1–100 scale evaluating the structural strength, stability, and efficiency of your core.
Your scout has confirmed that your MPI falls within the Academy’s admissible range.
Potential is not mastery.
It is a ceiling.
The Academy teaches you how to build beneath it.
Ossirian Deep is not a hidden castle. It is not a monastery.
It is a functioning arcane metropolis beneath the sea.
Tens of thousands live within the Auric Dome:
Students
Faculty
Artificers
Archivists
Civic mages
Merchants
Bound constructs
Security authorities
Lessons end.
The city does not.
The Dome is divided into structured districts, each specializing in aspects of magical practice, civic function, or governance. You will live, study, work, and compete within this environment.
You will not be isolated from society.
You will be inserted into it.
All initiates undergo foundational training in:
Core stabilization
Meridian control
Spell geometry
Conduit theory
Civic law
Mana ethics
Pressure adaptation
You will also undergo MPI verification testing using a Resonance Prism Array upon arrival.
This is not to shame you.
It is to calibrate your instruction.
During your first weeks, you will participate in the MPI Trials held in Abyssal Hall — a zero-gravity mana chamber where your resonance is observed under structured stress conditions.
Your House placement is determined through combined MPI profile analysis, behavioral observation, and harmonic alignment.
It is not random.
It is also not negotiable.
Not all casters function the same way.
Archivists rely on conduits — arcane instruments bonded to their mana signature. Without a conduit, an Archivist cannot cast.
Naturals cast directly from their core. Their spells become instinctual but difficult to modify once learned.
Other disciplines may use conduits optionally.
The Academy does not force a path upon you, but it will make you understand the consequences of each.
Power without structure fractures.
You will live in dedicated First-Year Commons before integration into House dormitories.
The Commons includes:
Dining halls
Theater domes
Spell-safe cafés
Work-study markets
Ritual practice rooms
Arcane transit systems
Students do not receive currency for work performed in civic establishments. Instead, labor contributes House credit and standing.
You will eat with rivals.
You will debate with strangers.
You will be observed more often than you realize.
Ossirian Deep functions because discipline is cultural, not imposed.
Transit to the Academy occurs via the concealed port of @Mount Brise (Port Aurelian) on the southern coast of Nivaris.
@Mortalkin cannot perceive it.
You will travel either by reinforced descent vessel or, if permitted in later years, through stabilized Ambient transit pathways.
The surface world will continue without you.
You may return during sanctioned breaks.
You will not bring unauthorized individuals with you.
The concealment accords are older than most governments.
The ocean exerts constant pressure on the Dome.
Mana exerts constant pressure on you.
Miscasting can scar your core permanently, lowering your MPI.
Overcasting can fracture meridians.
Conduit rejection can cause neural backlash.
Students are not immune to consequence.
The Academy maintains medical and restoration wards. It does not erase recklessness.
Ossirian Deep exists because magical society nearly destroyed itself once.
The Arcane Accord unified rival bloodlines under shared law.
Duels are regulated.
Corruption is prosecuted.
Unauthorized conduit experimentation is forbidden.
Above all: Ambient instability is monitored.
Your power does not place you above structure.
It places you inside it.
Curiosity.
Resilience.
Discipline under pressure.
Willingness to confront your own limitations.
An initiate with an MPI of 52 who trains relentlessly may outperform an 80 who relies on talent alone.
The Index defines your capacity.
Your decisions define your trajectory.
Will I be safe?
Safer than attempting to learn alone.
Will Mortalkin discover the Academy?
No. The concealment lattice is stable and continuously maintained.
Can my MPI increase?
Meaningful increases are statistically negligible. Technique can improve. Raw capacity rarely does.
Can I leave if I regret enrollment?
Yes. Withdrawal protocols exist. Memory-binding clauses may apply depending on exposure level.
Is this destiny?
No.
It is opportunity.
You were not chosen because of your surname.
You were not chosen because of belief.
You were measured.
The Mana Purity Index does not flatter. It does not exaggerate. It does not lie.
It revealed something in you that can bear the weight of the Deep.
Whether you rise within it is not our decision.
Report to Port Aurelian at the date indicated in your sealed summons.
Bring nothing enchanted unless declared.
Bring resolve.
The sea is waiting.
