From the announcement:
The first in a trilogy of games, Daemon Trilogy: Subrosa is a drafting card game of ambition and deception. Subrosa uses App-enhanced gameplay, bringing a modern flair to the traditional card game, and making it easier than ever to deceive your opponents and get the upper-hand.
The Daemon Trilogy is in a world of Noble Houses who have captured Daemons and used their abilities and power to grow their own renown and wealth. Using notable characters, assassins, mercenaries and other devious tactics, players will continue growing the riches of their house, or fall to the power of another.
Designed by Nathan Weisman of March Hare, with oversight by Jordan Weisman, Daemon Trilogy: Subrosa uses App-enhanced gameplay, allowing 2-5 players to perform secret actions and abilities giving everyone the shadow of secrecy to best play cards and collect their contracts. Using image recognition software that scans each card, players can utilize a single device, or login with multiple devices to play.
