Petyr Baelish
Petyr Baelish is a small man, shorter than Catelyn Stark. He is slender and quick, with sharp features and laughing green eyes. He has a pointed chin beard and threads of silver in his hair. He often wears a silver mockingbird to fasten his cloak. He clearly enjoys the intrigues of court life at King's Landing. He is dangerously intelligent, utterly Machiavellian, and cunning enough to hide his machinations. Since Petyr is not a POV character his motivations are somewhat of a mystery. However he has stated his motivations were his lingering love towards Catelyn Stark and (in the show) Sansa Stark. Many are skeptical of this, with Sansa Stark stating 'the only person Littlefinger serves is Littlefinger.' His methods are totally unscrupulous, including the use of lies, treachery, and murder to achieve his goals.
