From the campaign preview:
The Yates family is desperate because of an old curse which lies heavily upon them. Only the best visionary will be able to find the roots of the curse and helps the family by breaking the curse.
To do so you need to collect time cards, connect your mental power at the right time with different parts from the family's past and use your visionary power. Receive vision stones and put together visions and your personal master vision to gain mental influence. The visionary with the most mental influence wins the game.
The campaign is set to launch on the 25th.
