Confused by classification of champion region
Heimerdinger is from Bandle City but is listed as piltover due to his alliance to piltover, and the fact he is located there right now. (doesn't mean he isn't allied to bandle city, though) Rek'Sai is allied to the void but is currently near shurima, but is listed in void anyway. (in fact all the void champions probably aren't in the void right now)
This is where things get confusing
Blitzcrank is from Zaun but left and never liked them, yet is still listed as Zaun. Janna does not agree with Zaun's ideals and is allied with piltover but is listed as Zaun (though she might be there right now) Kassadin isn't allied to the void but is listed as a void champion anyway Lulu left bandle city but is listed in bandle city anyway, and Veigar is also listed as bandle city Orianna was in piltover, then moved to zaun, then left entirely, but is listed in piltover
So how is a champion's region defined?
Also Lulu's lore describes bandle city as boring while bandle city's region page describes it as extremely colourful vibrant by human standards. Is the glade like, constantly epileptic then?
