Yes, although players have their own objectives to complete, all players work together to beat the game.
From a gameplay point of view there is none, your character is in the booth.
No, just the action on the bottom of the card. You only get to perform the top action (once) when you complete an objective.
The top action is taken once at the time of completing the objective, the bottom action can be used once during the action phase of your subsequent turns.
Yes, there is no limit to how many you can carry and there are some objectives that require you to carry more than one.
It's highly unlikely more than one or two would be on their correct locations, however if more than 3 are on their correct location we would advise you shuffle all Personage of Historical Significance cards and deal them out again.
No, nice try!
After an Historic Location has been fully fixed, the Active Player takes the corresponding Personage/Location card and places it under their Character card with the Personage of Historical Significance showing. From their following turn, that player will have access to a Triumphant Die for each Rift they have fixed, still abiding by the four dice limit.
No, you slide the completed objective card under your starting reward so you can see both, and gain both bottom actions from then on.
It's not possible to use both in a single turn, a location cant be both fixed and red, you would pick the action that is currently suitable.
No, you just need to have performed the objective over 3 rounds, they don't need to be consecutive.
Yes, you can only lower the rift on a space you are on, and in this case you need another player on the same space.
In order yes, but the turns do NOT need to be consecutive.
No, once a Person of Historical Significance has been returned to their correct historical location, they remain there for the rest of the game.
