I have Neptune exactly over gacrux at 6.47 of scorpio this has initiated a strongly secretive Christain theme in my life.Especially when Neptune transited my ascendant ruler Mercury.
An interesting observation concerning Gacrux is that when armed soldiers in
Manila Philippines were ordered by Ferdinand Marcos to kill demonstrators on the streets, who had been holding rosaries & praying the rosary, a strange thing happened.The virgin Mary appeared in front of the soldiers & told them
not to harm her children.So overwhelmed were the soldiers by the apparition that they turned against Marcos.
This occurred in 1986 as Pluto was over gacrux.

with Neptune over Gacrux the Pope announced changes i.e. the second Vatican council which relaxed the strict rules for nuns which caused up-to 90000 nuns to leave their calling unhappy with the changes.
The second Vatican council seems to be the reason the apparition of Mary at Fatima, wanted the secrets exposed before 1960 but the third secret remained hidden some speculate it is about the smoke of satan entering the Vatican, & the subsequent abuse scandal.A mystery very Neptune in Scorpio we will never know the third secret.
The other theme of Neptune in Scorpio is Martin Luther King's famous speech I have a dream the Pastor was assassinated leading to mass riots whilst Neptune was in Scorpio
