7 Days to Rigel is a free and open-source roguelike murder-mystery game written in seven days for 7DRL2019, and a proof-of-concept for a paper on procedural narrative generation and the use of promises in logic programming to circumvent the expression problem, to be released at an as-of-yet undisclosed date in the future.

It's built on Python 3.7 and python-libtcod, leveraging kanren and parts of code from (yet) unreleased personal projects Vibropyke and an early prototype of LorxuLang, for the logic programming parts. Those parts will later on, hopefully, be published as a full-featured Python logic programming framework.

Parts of the code (mainly sdrl/game/actors) were adapted from an unreleased personal research project on procedurally generated narrative, Vibropyke, and were originally licensed under the GPL-compatible Mozilla Public License, v. 2.0. As they are distributed here as a part of 7 Days to Rigel, they are also licensed GPL, in accordance with the MPL's clause on Distribution of a Larger Work (3.3).
