So Ryze's Intro Paragraph's here, and it gives a bit of insight in to Runterra's origins...
>_ 'Take care with this world. What is made can be unmade.'' _ Widely considered one of the most adept sorcerers on Runeterra, Ryze is an ancient, hard-bitten archmage with an impossibly heavy burden to bear. Armed with a boundless constitution and a vast array of mystic knowledge, he spends his life searching for World Runes - fragments of the raw magic that once shaped the world from nothingness. He must retrieve these glyphs before they fall into the wrong hands, for though they were once used to create Runeterra, they also have the potential to destroy it.
So apparently the world was forged by an incredibly powerful magic and the remnants of said magic are known as World Runes. Said World Runes are also likely to be the runic power that defined the Rune Wars.
Thoughts people? I feel like we'll definetly get more with Ryze's full lore, but this is an interesting bit of information.
has a sword with the power of a nuclear bomb?
and his star making?
