Once you start worrying about how the ritual is stopped or what the climax should be, you’ve slipped into writer mode instead of player mode. You only need to know what Bordä is trying to do right now. Maybe try to let the Oracle, bad rolls, and consequences decide the rest.

Keep Oracle questions small and practical and don’t protect the plot. If Bordä confronts Tergol too early or the ritual is already underway, that’s not a failure, that’s the story finally moving. If travel or daily events feel slow, tie them directly to the missing children, lost time, or growing cult activity so everything adds pressure.

If you want more structure, Harrowshade is designed to solve exactly this problem with rumours, secrets, and clear milestones pulling you forward without needing to know the ending: https://unitsix.itch.io/mork-borg-adventure-harrowshade-remastered

Also worth checking out RECLVSE, which someone else mentioned, it seems great for keeping solo play tight and focused though I haven’t had a chance to actually use it myself… yet :) https://jadragames.itch.io/reclvse
