Sejuani Update!
We are now approaching a complete Freljord-Update, especially with the new Sejuani Bio. I will be dicussing the update so read it before, dont let this be a SPOILER :) https://universe.leagueoflegends.com/en_PL/story/champion/sejuani
So Sejuani is now the leader of the Winters Claw, tho before it used to be her Mother Kalkia who left the tribe for a man(Udyr no doubt). Now this part is very odd, because Udyr mustve been very important to Kalkia for her to leave the tribe. Most importantly a Warmother is always there for the tribe, she is the "Head" of the tribe and it is extremely careless and highly unusual that a Warmother would just leave her tribe, even Grena stuck to the Avarosans through bad times.
With no Leader, the tribe fell into chaos and was probably close to starvation and, Oh look at that, all roads lead to Rome Frostguard ;)
So the Frostguard helped, with food and protection (how ironic)
Sejuani never liked the Frostguard and when her mother returned and Sejuani took her place as Warmother, she purged the tribe from Frost Priests and the Frostguards control.
Now everyone who denied the faith of The Three saw the Winters Claw as their true purpose, to undermine the Frostguards influence.
Sejuanis current obsession isnt to fight the Frostguard tho, she wants to challenge Noxians and probably expand her territory there (which is also ironic since this plays into Lissandras plans, its just that Sejuani does the work for her). All in all great update!
