Game Of Thrones: 10 Most Powerful People Going Into Season 6

2. Petyr Baelish

Does anybody know what he's up to any more? Littlefinger has travelled from North to South, East to West, picking up treacherous allies and noble enemies along the way. He's playing the long, long, long game with no clear end in sight. Baelish's next move is a complete unknown but given his track record, you can expect it will be earth-shaking. Baelish is such an unknown quantity, and that's what makes him extremely dangerous. He's the ultimate puppet master with an end-goal that still isn't completely apparent. Sansa's escape from Winterfell was surely not part of his plan (surely?!) so you can expect Littlefinger will head back to the North in an attempt to limit the damage from that mess. But Baelish's greatest strength is his improvisation. He can adapt to any situation, and by the end of Season 6 he'll no doubt be more powerful than ever before. This is Baelish's world, and they're all just living in it.
