My Idea on a new lore for Taric
I got one I hope you guys might like, also this is my first time writing this kind of thing so any constructive criticism is welcome: During his travels among the lands of Runeterra, Taric had the misfortune of running into Lissandra, after a long and fierce battle she cast him inside a prison made of true ice and was left to die, but unbeknown to Lissandra, the willpower of the gem knight was far stronger than the magic cast upon him, he used the might of earthen magic to break free of his icy tomb, but as he was catching his breath, he began to feel a stronger connection with the earthen magic of Runeterra since being summoned from his home-world, and he set off to forge a new set of armor to attune to this new strength of earthen magic, and with this power he vowed to Preserve and Protect any ally in need.

(Brand was imprisoned in ice and she lists him as an enemy,volibear had a vision that may be related to her,trundle doesn't like to work for her(and might be the troll that fell into her trap) and while she probably never met gnar,she serves the watchers who were most likely the ones that attacked gnars family).
The only people from the freljord who don't seem to have her as a personal enemy of some sort are 
and maybe 
(although nunu was once a member of the frostguard that ran away from them due to their cruel nature,so that one is arguable)
