A Game of Thrones: Hand of the King (2016)

Description from the publisher:

The king has called for a lavish feast and tourney, the likes of which have not been seen in the Seven Kingdoms since the days of Aegon the Conquerer. What's more, the king has declared that at this feast, he will choose his new Hand — and you have a chance of rising to this lofty position. Of course, you're not the only one with eyes set on becoming the power behind the Iron Throne. In A Game of Thrones: Hand of the King, you need to scheme and backstab to outwit your opponents, and you need the help of Varys, the Master of Whispers, to do it.

Hand of the King is a fast-paced card game of conspiracies and sudden twists of fate for two to four players, challenging each of you to gain the most support among the twisted intrigues of the King’s Landing court. Each turn, you send Varys to do your bidding, moving through the court and inciting iconic characters from A Song of Ice and Fire to support your cause. With the help of some companions and crafty alliances with other players, you just might rise to become the king's new Hand!

In more detail, players move Varys in orthogonal lines in a 6x6 grid, stopping it on a character token, then collecting that token and any other character from that House that you passed over. Possess as many characters from a House as someone else, and you claim the banner from that person. Collect the final character from a House, and you immediately use the power of one of six companions; since the game contains fourteen companions, the mix of powers will differ each game.
