Saddest Champion Lore?
If you ask me, I'd have to say it's probably Yorick. But you don't really get that without his review for the league
> "Yorick could barely recall his early years in the Shadow Isles, diligently tallying the passing days, then months, then years. When the inner walls of his cave were nothing more than a maelstrom of crooked lines, he stopped. There was no more point to counting days in death than counting breaths in life. He wondered briefly how many lifetimes he might have tallied – another utterly useless exercise. " > > "The shovel rested neatly atop the body, clasped beneath its folded arms. The face -- that face he should have known -- was his own. It was the face of innocence, hope, sadness. It was a face so early on its journey, already convinced it had seen the end. > > And Yorick didn't even recognize it. " > > " Normally, I would stand here wearing the face of someone you once knew, but it seems you've forgotten everyone. "

lore yet.
I mean, he first get betrayed by his former friends, get pushed into a weird black ooze, just to find himself on the oceanfloor in complete darkness fused with a diving suit. Even in his quotes you can hear how mentally damaged the poor guy is:
"The endless march."
"Forward. Forward."
"Left to die."
I would never want to have his fate (though big daddys are awesome)
), never finds a home (The League of Legends), and his Tantrums become stronger for it.

to the new garbage is sad too.
He was betrayed and killed by his best friend,for reasons he can't understand.
His whole family and the kingdom he loved so much were all destroyed(even worse he had a vision of his families last moments),when he only wanted the best for his kingdom.
