The royal baby has arrived in London, and the young heir has an overwhelmingly emotional, watery chart with a Cancer Sun.
Never mind his secretive Scorpio ascendant; he'll be hugely self-protective since his sensitivity to the real world will be so acute. There's indeed a risk of him living in his own bubble and refusing to connect with the outside world. Since his birth chart includes a Water Grand Trine -- in triplicate! -- he could become an escapist. However, his Water element comes in addition to being creative, which could well turn out to be a force for healing, since personalities such as his usually a possess empathy for others' suffering.
Since he could turn out to have a massively introverted personality, his saving grace is an enthusiastic ninth house Sun, plus several Cardinal planets spilling over with initiative that will motivate him to travel and develop a keen interest in foreign cultures.
All three legs of his Water Grand Trine are in hard aspect to other planets, which will help jolt him out of his cocoon. Neptune opposes a ninth house Venus in Virgo, which will lend him talent in the arts. Jupiter, Mars, and Mercury also oppose a second house Pluto, so financial matters will be of considerable interest to him, perhaps even turning into a minor obsession.
Delving more deeply into the royal baby's birth chart, Saturn in Scorpio squares the full Moon of the Cancer Sun and the Capricorn Moon. His Venus is inconjunct to his Moon, something that's marginally similar to Prince William's own Venus inconjuncts ... so he may experience strains when it comes to fitting in socially.
With the Moon and Neptune in his third house, he'll be daydreamy and find it difficult to express what he really wants to say -- especially on an everyday level.
Having six planets in Water and three in Earth will help ground him. Not having any planets in Air, however, will make it difficult for him to detach from his feelings and see things coolly. With only one planet in Fire, he'll lack in trust throughout life. He'll have a great deal to give in terms of helping others, but he'll have his emotional problems along the way since his is not an easy chart.
Finally, he'll meet the love of his life when he is 30 -- probably a foreigner, as his progressed Sun will be conjunct his ninth house Venus at that time.
