UPDATE: We have created a Writing Guide Template! This is to help organize all the concepts and prompts. Available in Google Sheets, Excel and Open Document formats.

Threads of Lachesis (TOL) SRD, is a system reference document to create games with branched random Prompts that the player organizes into a cohesive sequence via a single roll.

Games created with this system can hyper-focus on the span of a second, an hour, a day or zoom out and view the span of a family’s generational legacy, a civilization, or a galaxy. It can be used to quickly create rich and varied character backstories or used for world building to generate the major and minor events of a nation or continent.

What This Isn’t

Threads of Lachesis SRD is not a complete game. As such, this document is not player-facing and does not include sections, verbiage, or Prompts to play a specific game.

This SRD was created for the 2021 TTRPG SRD Jam.

Eventhough I help out a little, I have to say that I can't wait to use this SRD to make a game of my own!
