Content Conventions

The World of Trid is a decades-old setting created with and for the red Basic and blue Expert rules. This makes it compatible with Labyrinth Lord, Basic Fantasy, and Old-School Essentials (OSE). For clarity and consistency, the OSE Classic Fantasy rules may be considered authoritative.   To that point, the World of Trid employs a great number of house rules and variants external to the rules. Players and referees are encouraged to discard these in favour of the classic rules-as-written or to substitute their own modifications. Likewise, when a rule is not specifically addressed herein, assume that it's handled as described in either the B/X books or the OSE Classic Fantasy volume.  

Formatting

Trid is presented in the short-form and bullet-list format found in Old-School Essentials. As those familiar with the concise nature of the classic rules well know, this abbreviated treatment can introduce some nuance when interpreting certain rules or effects. We consider this a feature, not a bug, as it gives players and referees latitude to interpret the material to suit their own style of play.   Open Game Content: The material herein is published under the terms of the Open Game License (OGL). Pages tagged as #ogc are considered open game content (OGC) and may be reused or repurposed under the OGL's terms. All OGC content is accompanied by Section 15 attribution at the article's end. Conversely, pages tagged #productIdentity are specifically designated as Product Identity and may not be reproduced under the OGL.  

Additional Sources

While based firmly on the classic rules, the World of Trid is enhanced with elements from these expansions:

• Old-School Essentials Advanced Fantasy: Player's Tome
• Old-School Essentials Advanced Fantasy: Referee's Tome
• BX Options: Class Builder
• BX Options: Alternate Magicks

 

Terminology

Attribute Checks: Checks against one of the six attributes (e.g., a STR check or a WIS check) are arbitrated with the Attribute Check variant.   Person: Use of the term "person" is deliberate when referring to targets affected by certain spells or spell-like effects (q.v., Monsters in the OSE rules).   Player vs. Character: Players are the real-life people sitting around the game table throwing dice. Characters are their avatars in Trid, likely (and it is hoped) up to no good.   Referee: For clarity, the term "referee" denotes whomever is running the game, by whatever title is designated in the ruleset used.   Skill rolls: When an outcome has an "X-in-6" chance of success, we use "X/6" to save space (e.g., "2/6" means a 2-in-6 chance; "3/20" means a 3-in-20 chance).  

Organisation & Formatting

The World of Trid is purpose-built for use with either the two-volume Basic/Expert D&D ruleset or the Old-School Essentials Classic Fantasy rules. The following conventions provide a consistent presentation of Trid's many wonders:  

Site Structure

The World of Trid is partitioned such that referees can pick and choose the parts they like:  

1. Gazetteer: A solid, but intentionally high-level perspective for referees who want a classic fantasy foundation upon which they can build.
2. Tridopedia: An encyclopaedia of Trid's people, places, and things for referees who want more setting-specific context with the flexibility to inject their own creative elements. Available by subscription, the Tridopedia is the tower built upon the Gazeteer's foundation.
3. Sandboxes: Fully statted mini-settings for referees who want ready-made hexcrawls to run as-is. Avaiable by subscription, sandboxes are fully furnished floors of the tower.
4. Rules Tome: Trid-specific conventions and optional house rules that referees can use or ignore as desired.
