Archivium Codex 05 The Hidden Curriculum

Codex 05: The Hidden Curriculum (55 pages)

Knowledge has a cost. Are you willing to pay it?

Not all lessons are listed in the syllabus. Not all knowledge is meant to be shared. Somewhere between the dusty tomes and whispered rituals lies the Society’s true curriculum: hidden paths of study, mentors who trade in secrets, and rites that will change you forever.

The Hidden Curriculum is a 55-page expansion for The Archivium that transforms Society play into a long arc of magical progression and consequence. For the first time, your Custodian can apprentice under mentors, experiment with forbidden rites, and shape the future of the Archive through their own studies.

What’s Inside

• Influence Milestones Expanded
  At Society Levels 3, 7, 13, 18, and 23, draw from new prompt tables that explore secret debates, rituals, schisms, and revelations. Each milestone pulls you deeper into the Society’s mysteries.

• Fields of Study (15 Disciplines)
  Choose your magical path at Influence 7 and again at 18. 

  • Temporal & Celestial Studies

  • Occult Binding & Pact Studies

  • Hauntology & Echoes of the Past

  • Theology & Sacred Mysticism

  • …and 11 more, each with its own flavour and dangers.

• Mentors & Rituals
  Every field introduces Subject Matter Experts: eccentric academics, disgraced researchers, or strange presences willing to teach. Each comes with signature rituals, requirements, and consequences.

• The Price of Power
  Magic in the Archivium is never free. Rituals demand time, rare materials, or personal sacrifice. As your Custodian advances, the Archive leaves its mark, physically, mentally, or socially.

Why This Codex?

If The Academic Register made university life more rigorous, The Hidden Curriculum makes Society life more dangerous. It shifts your Archivium play from cozy horror with a hint of conspiracy into occult academia, where every breakthrough comes with a cost.

It’s the natural endpoint of the Archivium expansion line: the long-promised magic, finally in your hands.
