You are Loras Tyrell (Butterfly)!
“When the sun has set no candle can replace it.”
“Knight of the Flowers”, I know, not a particularly intimidating moniker, but it does perfectly describe the dual nature of your Butterfly grace: it can be used to produce beauty or kick some serious ass. You’re gentle by nature—your best fighting is displayed during the pageantry of tournaments—and most of your time is spent vacillating between fighting for those you love (Renly) and letting those that love you (Margaery) fight your battles.
