I have another query regarding this. Are there any indicators of specifically whether it should be foreigners or travel? I get very attached to my area, but I also feel the need to have foreign influences, or maybe English people who's parents are foreign-but does staying here(place I grew up) have to mean I'm stuck in South Node? I tend to be attracted to people with foreign parents also.
Also regarding travel, how far does it have to be to qualify as north node travel not south node?
Astrology isn't that specific. North node in the ninth house could indicate any or all of those things... or possibly none of them, because its range of meanings is even broader than that. And it's important to consider not only the house placements of your nodes, but also the sign placements, and the placements of the node rulers. Your north node, being in Leo, is ruled by the sun--and your sun is in the same sign and house as your south node, in four degrees orb of conjunction.
When the north node's ruler is sharing space with the south node, this isn't a lifetime to get rid of your south node patterns, but to build on them, finish what you started, do what you didn't have the chance to do before. When your sun is in the same sign and house as the south node, what your core personality needs most for its own growth--that is, what the sun represents--is quite similar to the south node message. There may be some tweaks needed, but the basic picture is the same. And when your sun and north node ruler are one and the same, having it with your south node doubles down on that message.
In addition to the north node itself representing what you should work towards, the north node's ruler also represents that. Here, it helps to look at the archetypes of each sign. Aquarius is the Truth Sayer, Rebel, or Outsider, to name a few archetypes. Leo is the Child (looking at the world with wide-eyed wonder), or Ruler/King/Queen, or Performer, to name some of its archetypes.
Third house is about communication--speaking, observing, language, self expression, sharing stories, those kinds of things. Combined with the Truth Sayer archetype, and lots of planetary placements in your third house, it looks like storytelling is an important part of your life. That might be literal storytelling, or that might be a tendency to tell it how you see it, or it might be something else along those lines. Your south node being placed there tells us that was also true for you in the past life(s) that you're building on.
There's much more to your south node story--lots of aspects, plus two rulers, whose placements and aspects give more detail--but I don't have time to go into that right now (could later if you're interested). Your north node placement, meanwhile, suggests building and expanding on who and what you were in the past. Ninth house is all about self expansion. Travel and foreigners are ninth house indications because traveling and experiencing foreign cultures is a way to expand your mind and sense of self--and so is interacting with foreigners who visit or immigrate to your country. But those are not the only ways, just some examples.
When the south node is in Aquarius and north node is in Leo, that usually indicates a need to make your message heard. Aquarius, being the truth sayer/rebel/outsider, risks being left out in the cold, their ideas too far outside social norms to gain much purchase. For Aquarius (and I'm talking about the Aquarius archetype here), that isn't necessarily a hardship, because Aquarius does not feel any personal need for social acceptance, just for generating ideas and being free to live them. (Aquarius suns and others who strongly manifest Aquarius typically do need social acceptance, just like everyone else, but nobody is one sign archetype--I'm just talking about the sign alone here.)
Leo, in contrast, needs social acceptance to live. (Again, this is the sign's archetype, not necessarily true of Leo sun people or others with strong Leo, because they also manifest other archetypes.) It's the performer, responsive to the responses of its audience. Leo needs to be heard and will insist on making itself heard. That makes it the perfect antidote to an Aquarian message fallen by the wayside.
So your north node placement is really telling you two things: expand yourself and make your voice heard. How you do it is up to you.
