So as we all know the mountain was created by being pulled upwards. But what was there before the pull happened? There are circular cravings all over the place which are believed to be celestial maps and patterns. Then there is the greenish metallic stone that fell long ago. It's interesting how this place where the mountain currently is was so important that the real Targon tried to pull it physically.
Is it stated that Targon pulled it up? Or maybe it's just a side effect of the whole World Runes thing and that is just the Aspects 'arrived/settled' as it was the first thing they saw, it being so high?
Or maybe just a side effect of when they arrived.
Seeing that people who climbed targon came back as aspects, it may have been an advanced magical prison for otherworldly beings, if i recall correctly, Aurelion Sol was also tricked and trapped or perhaps bound on targon. As for the patters around it, take the patterns in Sorkas E spell and make it bigger... They keep keep whatevers resides there binded and powerless, such as Sorakas E silences you and binds you.
if i know my rocks...
malphite probably ran into a volcano and ended up creating mount targon.
