Introduction

Custom Rules for a Custom setting

The World of Trid is a global sandbox of sandboxes, built with the Basic/Expert D&D Implied Setting in mind. By extension, the material herein is compatible with Labyrinth Lord, Basic Fantasy, and Old-School Essentials (OSE). In that vein, Trid is easily stretched to accommodate just about any OSR game, and we’ve relied on the Principia Apocrypha as our guide.

That said, our Rules Tome assumes you’re familiar with common OSR conventions, like the classic fantasy game genre, dice nomenclature, and the myriad answers to the common question, “What is role-playing?” To get the most out of the Rules Tome, we recommend the resources below.

Game SYstem & Core Rules

The World of Trid is written for what we’ll term the “classic rules,” which refers equally to the:

While based firmly on the classic rules, the World of Trid incorporates elements from these expansions (none of which are required for playing or running campaigns in Trid):

Content 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.

Terminology

Attribute Checks: Checks against one of the six attributes (e.g., a STR check or a WIS check) are arbitrated with our ability check mechanic.

Person: Use of the term “person” is deliberate when referring to targets affected by certain spells or spell-like effects (q.v., Monsters).

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).
