Ponderings about Shurima (Realms of Runeterra spoiler warning).
Over the holidays, I was lucky enough to be gifted the 'League of Legends: Realms of Runterra' book as a gift, because I'm the League nerd in my circle of friends. I've just recently finished reading the thing from cover-to-cover, and I gotta say, if you're a fan of the lore, it's a great book.
Anyway, the thing is full (5-6 I think) of short stories, one pertaining to each well known area of Runeterra, such as Demacia, Ionia, ect. The last one I read was about Shurima. Mild Spoiler warning, but Azir is featured in the story, and at one point, he describes what happened during his Ascension. It goes like this:

"On the day of my Ascension, just as I planned to free Shurima's slaves, he betrayed me. He cast me into the killing fire as he took my place on the sun disc to steal my godhood. I was supposed to ascend that day, but instead Shurima fell and devastation swept ver the land. An empire that had ruled the known world for centuries was wiped out in the blink of an eye by a terrible cataclysm that laid waste to the earth and burned away the waters."
"Is that why Shurima's a desert?"
Azir Nodded.

So, the question is, what was Shurima like before it got blasted? It's pointed out here that Xerath is the one that made Shurima a desert...and all through out League's known history, it's been referred to as a desert-like place. All of their champions pull from that visual style and culture...but Azir shouldn't, right? Because he comes from a time that predates the sands and the deserts.
Just makes me wonder what the culture and region was like before that.
