Stellium

On average you should have 2-3 factors per zodiac sign, like Aries, in the First House, which Aries rules in the Natural House system. If you have more than 3, you have a stellium. An unusually high ‘count’ in that sign and house. So, Aries is going to dominate your personality, more than it does other people, and the First House of image, presentation, appearances and reputation will play a much bigger part in your destiny.
