The deal with summoners and Lore.

I've been thinking about this little to nothing is known about the actual summoners ( Us technically ) summoning the champions into the rift. We all know each summoner summons a champ and the champs fight to settles wars and differences. But how do you become a summoner and why do they wield such great power. To control the likes of xerath anivia and brand who are all basically Gods in lore terms. Also i feel like we dont really dive into that area. While we all know that summoners summon champs but how is this even possible. And how do they even control the champions. Like foreal so are the champions technically puppets and they ( we ) are pulling the strings while they are in a match. So is it actually like when we are playing them in which they are basically useless without the help of summoner in the summoners rift. So these great powerful beings cannot move unless a summoner is present to control them. And if the summoners are controlling them how does this actually solve the problem of wars and such if the battles aren't actually being fought by the champions. I googled this and on the lol wiki it said riot said the summoners are deprecated along with the institute of war. So does that mean summoners don't actually exists? Riot needs to further explain how summoners work in the lore because the little bits and pieces we can gather from champions lore's are not enough. Where did summoners come from are they eternal have they always been. Are summoners human or some different race all together. The concept that these people summoners have complete control over Runeterra to the point when they can stop the rune wars themselves are basically force everyone to join the League of Legends is crazy. With people strong lore wise like Aatrox, Lissandra, and Brand im surprised there hasn't been an uprising yet. Are they that afraid of summoners not to have done anything at this point. The best way to deal with this is to release a summoner champ. Of course he would be a mage but in his lore explain what a summoner is how they control champions and how a summoner such as his or herself could become a champion that is controlled. If anyone see points that are wrong, correct me because i really want to know about this thanks.
