No matter what the Sun sign is, the influence of the sign of the stellium will have considerable influence on the total structure of the chart. In addition, the House it falls in will be an important area of life. Stellium give tremendous intensity to the energies represented by the planetary bodies contained within the configuration.
Usually, 4 or 5 planets isconsidered a Stellium. It intensifies the focus on the sign tenanted by them and converges the energies of all planets involved in an overpowering manner, lending a 'driven', narrow-focused, empassioned charisma to the individual, whose nature will be moulded by the general character of the particular planets involved and expressed through the sign filter in the areas of life indicated by their house placement.
The 3rd house , in your case would be intensified. This is the house of Relationships. – the lungs; short journey, correspondence, study. If the ruler is retrograde, you repeat yourself in communicating and often have to retrace your steps in travel. You also find yourself frequently asking others to repeat what they have said.
The sign reveals your attitude and style in communicating, your style of learning and group of basic knowledge.
It reveals how you relate to your environment, especially to the people in intimate or early life settings. The first speaks about the impression you make and the 3rd house shows how you interact. You can discover additional info about your relationship with brothers and sisters, especially your oldest sibling and/or the one who makes the deepest impression on us or on the rest of our family. It speaks of your neighbours and those friends close enough to be considered brothers and sisters. It points to your formative and secondary education and to the teachers you had during that time.
That should cover it pretty well .
