The Imperial System

The Imperial system, known as TIS for short, is a d12 based die rolling gameplay and drama system for RPGs. It aims to facilitate games with collaborative, co-created lore and history, built from a limited description of the world. As such, players should feel free to describe friends they know who can help with challenges faced, to fill out the details of a treaty between two peoples which can aid them in a situation, or describe how their personal history influences the story.

This system was created to run Triumvene, a cross-genre ongoing world created as a partner for the system, set in across a mix of high fantasy, low fantasy and hard sci-fi worlds. However, it was also set up to be generic enough to allow for any place, genre or setting to be used with it. If you want to use The Imperial System to run a campaign set in the world of Star Wars or Lord of the Rings; Game of Thrones; Critical Role's Tal'Dorei campaign; the WotC D&D adventures, or something entirely new from your own imagination, then you can do that too. It's a system geared around creating a style of play, rather than providing play for a specific setting.

With regards to the style of play, The Imperial System favours open-ended, exploratory campaigns, with players being given near limitless creative freedom. We create this through three main features:

  • The ability to re-roll any failed roll (at the cost of the GM building up points to kill any roll in future),
  • A system of magic which encourages flexibility in the use of magical abilities, and
  • A simple success/success with a complication/failure system for rolls.

Below you'll find a quick reference for players, covering the most common things you'd likely want to know. The detailed rules are everything after.
