Grimm Solitude is a solo rules supplement for the Vast Grimm TTRPG system. Grimm Solitude introduces the LASER Solo Gameplay Loop to enable solo play for Vast Grimm. Often, there will be a clear and natural flow of events, and you will not need to use such a rigid tool as the LASER. However, if you ever feel like you have gotten stuck, you can always fall back on the LASER to help you define the scene and your characters role in it.
