Mythras Encounter Generator: Glossary and Index Tools for Faster, Informed GMing

The Mythras Encounter Tool – feature recap for busy GMs (MeG) can be used for preparing encounters in Mythras, Glorantha, or general fantasy settings. But when you’re staring down 4,500+ entries—from broo raiders to allosaur stampedes—you may need more than just random searches.

That’s where the Glossary and Index Reports come in.

These tools will be periodically updated every couple of months, reflecting new entries, tags, and notes added to the generator. Whether you’re building sessions in a deep Gloranthan sandbox or just trying to figure out what the “Ojahl Acolyte” or “Afadjann Masarin” your players just provoked actually is, these resources can help you find the right encounter for your adventure.


🔍 Glossary for the Mythras Encounter Generator – Quick Reference for Busy GMs

The MeG Glossary helps decode the setting-specific, cult-specific, and rule-specific terms that show up in templates—especially from GloranthaMonster Island, and Mythic Earth.

Whether you’re new to the world of AgimoriAltinae, and the 7 Mothers, or just need a reminder of what AA or AiG means the glossary provides a one-line explanation for fast reference and may provide link to additional info under “More info” link.

Each entry is broken down by the words in its name and its tags, with helpful glossary-enhanced context where needed.

Features of Both Reports:

  • Entries sorted alphabetically by token words in names (e.g., “Troll”, “Wachaza”, “Necromancer”)
  • Tag-based navigation allows filtering by encounter theme, faction, or region
  • Highlights glossary terms and adds clickable “More info” links when available
  • Filters out common filler tokens (like “of”, “the”) for clean, readable indexing

Whether you’re prepping a troll caravan ambush, stocking a jungle ruin, or rolling up “just another bar night in Pavis,” these tools can help you move faster

These reports are updated in sync with the Glossary, every few months, to reflect the latest content, naming conventions, and additional notes in the generator.

Index. Click. Unleash doom.


Core Codex – Crafted Generic Opponents in MeG

Here is a set of opponents for Mythras Encounter Generator crafted using the Pyramid method from Mythras Companion. The idea is that on this tag (Core Codex) the opponents use exactly the culture and career skills from RAW when generating an encounter for the specific culture and career using Pyramid method. The skills that are enhanced as follows

  • 50 (30+4d10)
  • two skills 20+4d10
  • three skills 10+4d10
  • four skills 4d10
  • five skills 2d10

The skills are the once that would be most “suitable” to enhance for a career in this culture (this is of course always a judgment issue).

After this each of the skills the opponent has are enhanced first with 2d10 to reflect generic NPC history development.

The combat styles are given that would be suitable for this combo if any. The combo might have multiple that are selected randomly, might even have two combat styles. This should give a varied examples of combat style traits into your campaign.

The weapon choices are given that would be suitable for this profession in generic fantasy campaign.

The passions are then given that would be suitable for this culture/career combo. After that the description for a flavour is added.

Each of the Core Codex members are given folk magic and a random selection of spells suitable for the profession.

There will be more of these Core Codex members later – eventually all the profession pairs might be gathered.

This set could be used to clone a campaign specific civilized rogue instead of this generic civilized rogue.

With this method – some of the opponents reach master level and most reach veteran level. If you need lesser opponents adjust the skills by minus 20% to reach entry level opponents.

You can find these from the home page by writing tag name Core codex into search line.
