Your nodes straddle the house cusps. Being so close to angles, I think we can consider them on the MC and IC, which would make them tenth and fourth house, but there might be some hints of the ninth and third in the story.
If we look at this as the south node telling a past life story, we have two indicators that you were a highly visible person in your society: south node conjunct the MC, and conjunct your sun. Highly visible and someone people gravitated to, a leader. Given that your sun is right on the MC for this lifetime, it's likely that you are or have been a leader in this life, too.
For what kind of leader you were, we look at the sign placement of the node and what its sign rulers are doing. Pluto reinforces the ninth house indications by being solidly in the ninth house, in the same sign. Scorpio might indicate war, or any generally traumatic situation, or perhaps an occult society. Saturn in that picture suggests that you had some weighty authority and responsibility. Ninth house adds to the picture of religious or philosophical belief, or, if this is a war situation we're looking at, you could've traveled to fight. Perhaps you lead the invading army. Or perhaps you fought in a war abroad from where you lived.
Mars, other ruler of the node, being in distant, intellectual, and "movement of the people" Aquarius... that seems to me to suggest a cause. Twelfth house suggests downfall, maybe imprisonment, maybe dying in the attempt. Or, if we're going with the religious leader idea, removal from the world.
If you lived a past life where you were out in front leading the troops--literally or figuratively--and perhaps died in a war--you didn't get much chance to build a home, enjoy family life, or have stability. Your north node suggests those things. Taurus is all about security, stability, being grounded. Fourth house suggests building home and family. That could be done literally or figuratively. You might be driven to own your own home. You might want to do something that puts your hands in the dirt, like DIY or crafts or gardening.
You could build a family the traditional way, by marrying and having children, or a non-traditional way, like making a chosen family of friends. Either would serve your north node's purpose.
There's nothing here about having to stay low key and work behind the scenes. Given that all of your planets are above the horizon, you probably wouldn't want to. You still have a tenth house sun, indicating a need to be highly visible to others. The important thing is that, whatever else you do, you give yourself the space to ground, have security, and build home in some sense.
