More map investigating
When Kindred implied that they are called Ina and Ani in A Good Death in the west, those names had to be from Ionia. But it was also implied that War was raging around the area where Magga was. The two main side that we know of only is Noxus and Demacia. Now there could be other wars then those two factions. But its nothing we know of.
So Is Ionia closer to Noxus or Demacia? West implies Demacia from the old outdated map. But that could be entirely changed. But it Bard's video where the battle of Bard mountain was happening, the Noxians were there. So It is still easier for Noxus to access Ionia. Meaning that the Island(which is a large Island) is still in the Seas near Noxus. Or Most likely how Japan and Asia works, de-facto. But for the names "Ina and Ani" to be used one would have to think "Ionia."
But maybe the setting where Needlebrook and Jandelle isn't between the Demacian Kingdom and Noxian Empire. This could open up new areas we haven't even heard of yet. I was surprised when Illaoi is revealed to not be of Bilgewater, but a new place called Buhru. Which is indeed on one of the Isles of Blue Flame Isles. I find this a very good way to flesh out that Area of Runeterra. Kinda like how the Caribbean is.
Speaking of Blue Flame Isles, I hear of how the serpentine river was suppose to be near there? Well I do not think so. In Tobias's lore, it was implied that his people are called river folk. But when he left the area, he went to Bilgewater. It's not difficult to stowaway on a ship to the place of chance and fortune. I believe the Serpentine River is still on the mainland Valaran. As you can see on the Rift, the ideal geography of Blue Flame Isles isn't grassy plain lands. I would consider that canon since they made Butcher's Bridge a battle ground and we saw everything.
Also I want to talk about Zaun and Piltover too. As implied in Chronobreak, they are not two far apart. The river or lake that was there should still be there. But I believe that the two cities both have an extension that connects a meeting point to them. The outskirts of both cities. This is probably how that Piltie accessed Zaun so easily. I can't imagine him crossing some ungrassed path to the other city. It could be the outskirts or a whole entirely different place. I for one will not Believe that _ there is only two modernized cities in Runeterra._ There has to be at least 1 or 2 more.

About that shurima map, It seems Targon is below shurima, while Incanthia is east of the capital. So the desert remained the same location being on the southern part of Valaran. Targon can be accepted in this area because it is a mountain. And mountains reaches the skies so it is apparently gonna be colder up there than in a desert. I have not the slightest clue about bandle city or the Kumugu and Plague jungles. But then again it is just a little speculation... I really want to figure out the geography of Runeterra. It gives more in depth on the place.
