If you're a Leo (July 23 – August 22), chances are you act like a king or queen — no crown required. You have an ego, but you know how to use it. In social settings, you might hold court and tell tales of your epic-worthy exploits because you like being the center of attention and people are generally willing to give it to you. Leos don't need the affirmation and approval of others, but it makes them happy. It also makes them vulnerable to flattery. More is more to a Leo, whether it's fame, money, or power. And only the best will do. Your home, your clothes, and the parties you throw don't keep up with the Joneses, they make them jealous. Just watch you don't get yourself into debt.
House Lannister is a perfect fit for Leos. After all, they emblazon their family sigil, the golden lion, just about everywhere they can, and their House words are, "Hear me roar!" Even after Aegon conquered the Seven Kingdoms, they systematically used war, marriage, and money to elevate their status. They're said to be among the most attractive of the great families. Like Jaime, they're usually tall and fit with comely faces and golden blonde hair. Whether it's swordplay, foreplay, or wordplay, the Lannisters like to show off their skill. They display their conspicuous wealth and power with ornate armor and Casterly Rock, their colossal gilded castle. However, their vanity and hubris lead to their undoing.
