Spoiler: ALL I HAVE FOR YOU IS A WORD - TENET. IT WILL OPEN THE RIGHT DOORS, SOME OF THE WRONG ONES TOO
This is a game of 26 players. 20 Tenet Operatives (the town) vs 6 Sator Operatives (the mafia).
The game is split into two public timestreams of 13 Operatives each. Operatives may only post and vote in their respective timestreams. Temporal posting violations will be issued warnings at first. If the incidents continue, stronger measures may be taken.
Spoiler: HOW WOULD YOU LIKE TO DIE?
During pregame, the Sator Operatives may decide how to distribute themselves between the two timestreams. They may choose 4-2, 3-3, or 2-4. The town roles are then distributed based on this.
If all Sator Operatives are eliminated in one timesteam at any time night 2 and before, it will be announced in the respective thread.
Spoiler: YOU HAVE TO START LOOKING AT THE WORLD IN A NEW WAY
One timesteam runs forwards. This thread begins at the beginning of day 1 and runs like a normal game of Mafia - votes work normally.
The other timestream is inverted. This thread begins at the end of day 7 and runs towards day 1. In this game, all Operatives "begin" the day voting everyone else. An Operative is hammered in this timestream by a majority unvoting them. The flip then occurs at the beginning of day 7 and night "starts" at the end of night 6 and "ends" at the start of night 6.
Roles can shift or even completely change between the two timestreams. Operatives are informed what will occur to them if they invert.
When one timestream is hammered, it will lock, but the flip will not occur until the other timestream hammers as well. When there is a hammer, the deadline is reduced to 48 hours in the other thread and a warning is issued. Both flips will occur when both timestreams are hammered. Both nights run simultaneously.
Sator Operatives have a factional nightkill in each timestream, until the temporal pincer. Roles can only target Operatives in their own timestream.
Spoiler: DON'T TRY TO UNDERSTAND IT. FEEL IT.
Both timestreams have a public Turnstile that may be used once per day. An Operative is voted to use this in the same manner as the elimination. When the Turnstile is hammered, the voted Operative is immediately inverted to the other timestream. The Operative being inverted must be one of the votes on the Turnstile.
A timestream's Turnstile cannot be used a second time until the opposite Turnstile is used once, etc.
Spoiler: WE ALL BELIEVE WE'D RUN INTO THAT BURNING BUILDING. BUT UNTIL WE FEEL THAT HEAT, WE CAN NEVER KNOW
Both timestreams also have access to the Purple Room, a temporary neighborhood that opens each night. Each timestream may vote for an Operative to go to the Purple Room with an Operative from the other timestream in the same manner as voting for the elimination and Turnstiles. A new PT is created each night.
The nature of this Room, including who can access it, is ambiguous.
Spoiler: THIS IS WHERE OUR WORLDS COLLIDE
At day four (when the forwards timestream reaches the beginning of day four and the inverted timestream reaches the end of day four) the temporal pincer will occur. Both timestreams will merge into one main thread. From this point on, the elimination will take place in this thread. Sator Operatives will be reduced to one factional nightkill. Voting still works the same way (so inverted unvotes count as forwards votes). Roles will now be able to target Operatives in either timestream.
The separate timestreams and Turnstiles will remain open, as Operatives will still be able to invert and access the Purple Room each day.
Timestreams may move past where the opposite timestream started (i;e the inverted timestream could theoretically go to negative days).
Spoiler: WELCOME TO THE AFTERLIFE
As the timestreams move into the days already experienced by the opposing timestream, Operatives who died in those phases will return to life for one day only. Operatives return on the day matching the phase number they died in (so if someone died night 2 in the forwards timestream, they would return in day 2 of the inverted timestream). As these Operatives are only temporarily returned to life, they have limits upon them. They may not vote or use roles, and may only post 25 posts, each limited to 200 words. As well, they can only post in the timestream they are returning to - not the merged timestream.
Operatives eliminated in the merged timestream cannot return in this manner.
Operatives who died before the temporal pincer cannot access dead chat until after this "return" has concluded.
