I've been wrangling for the past week or so on the concepts of the Doom and Salvation tracks, mostly looking into other games that seem to use them. The Arkham Horror and Runebound boardgames are the only ones I can find that specifically feature them. I've not played either game, but the general idea seems to be about what I am looking for: when the track fills up, bad stuff starts happening. What I need to figure out is how the stress/Consequences model will be applied, and whether there's a need for two tracks at all, especially given that I'm using plot stress.
|Runebound Doom Track|
These work basically like Conditions from the Fate System Toolkit. The boxes are standard 1-stress/2-stress boxes. Once they're checked off, the Condition comes into play. What the Condition is remains hidden until it' revealed. We can assume that from a Tribe 8 perspective, the foundational ways the world is fucked up - you know, the bit about human civilization collapsing, the closing of the Fold, the Z'bri herding the survivors into the Camps, that stuff - are "below" this track. The universe is at a tipping point, and the things that wrack up the Consequences on this track are just accelerating the freefall.[ ] [ ] Condition #1
[ ] [ ] Condition #2
[ ] [ ] Condition #3
[ ] [ ] [etc...]
So far so good. The Conditions are setting aspects that make the world a less happy place to live in. For anyone who knows anything about the Tribe 8 metaplot, somewhere around the last of the unpublished cycles things is where the last of the Conditions are filled in. The world is about to be Taken Out unless something is done to start clearing the Conditions up. The Conditions themselves would line up roughly with the large events from each arc of the metaplot (there are about five of them). Of course, they don't have to be statically yoked to the Cycles. If the PCs convince the Keepers to resurrect some nukes and turn Hl'kar into a parking lot, and then turn around and unleash steampunk mecha to wipe out the Tribes, obviously the Doom track can fill up pretty quick
And when that happens, this is exactly what I will be doing
Now knowing what the Conditions are ahead of time is part of the "betting" against the Doom. On top of that, others' actions can obviously inflict stress on the track as well. So when the players are eyeing the two empty stress boxes on the Doom track as they try to channel the River of Dream through some Keeper device, they don't know a bunch of renegade Melanis Z'bri are also mucking around with the Sea of the Lost - and that both of them together are going to inflict enough stress to incur a new Condition. Getting a free invocation on that new Condition will probably feel like a consolation prize when they find out it's The Dead Have Risen and now they have a zombie outbreak to contend with.
Of course, in the early parts of the camp practically everything the PCs need to do in order to to help the Fallen survive are likely to be Doom-stress inducing events. Attacks on the Tribes, hunting Z'bri, messing around with things that they shouldn't, etc. aren't exactly things that would avert the impending collapse of reality. It's also not likely the outcasts are going to become a bunch of pacifistic saints and start acting for the good of all. For one, there's no way they'd survive a single winter if they did and two, it would be really boring.
Finally, we come to the "salvation" part. If the Doom track is like the universe taking a beating, then salvation means healing it. From a Fate Fractal perspective, this makes for a fun option: when the players do certain things, they get a chance to make a recovery roll for one of the Doom track's Consequences, or to clear some stress. Smaller actions would clear stress, while bigger sacrifices would rename and eventually clear Conditions. By the time the campaign is at the point where this is happening, the PCs are likely to be in a position to actively prevent others from re-incurring the Conditions.
Below is a rough version of the image I'll be using for the Doom Track in Roll20. The stress boxes are paired, with the white rectangle for the condition to be filled in. I'm trying to figure out what else to do with the real estate...I might create some spaces that can be used for other aspects and whatnot.
