How common is magic on Runeterra?
Never gave it much thought before, but with the retcon, it's important to establish this.
Most of these regions seem to treat it like it's a rarity.
Janna is the only Zaun to know magic.
Piltover combines it with tech, but we haven't seen anyone use magic by itself.
Veigar and Lulu are the only Yordles who use it.
Lux is the only Demacian to use it from what we've seen, and where did Garen get the ability to summon a giant light sword?
Katarina and Talon have limited teleportation magic, but where did they learn it? I assume Swain and LeBlanc learned their craft from the Black Rose, while Vladimir learned his from a hidden master.
Those that use magic in Freljord are either talking animals, like 
and 
, using a true ice weapon, or have some ties to the Watchers. Olaf just seems to be a badass, while Tryndamere was enhanced by Aatrox.
Magic seems exclusive to those connected with Ascendants in Shurima.
Ionia and the Shadow Isles appear to be the only places that freely practice magic.

) to empowering living organisms 
.
and maybe the Void champions (if void power is actually magic) are the only ones that spring to mind, everyone else either has a caviet attached or we don't know enough about.
Have the same kind of magic cause both Ashe and Sejuani are the descandants of Avarosa and Serylda the 2 sisters of Lissandra who got their power from the watchers
for example), all the hextech artifacts use magic, the true ice weapons are magical weapons, Summoners (not "THE" summoners of the old lore, normal summoners) can use magic, The Magelords where a civilization that used a lot of magic according to their name. etc
