Ith'Kra, The White Walker

Ith’Kra is a Freljordian Deity of the Winter, bent on keeping the Frozen Watchers- and their acolytes- from spreading their crogenic corruption to all of Runeterra. He wanders through the icy wastes, bringing the blizzards of the Freljordian Winter

In game, Ith’Kra is a sustain damage mage of the Cold, building stacks of Ichorous Ice, increasing his Mana Regen and Ability Power over time.

Bio
Once, Ith'Kra was warm, human... well, humanoid. He was a loving sibling of the Freljordian Gods. He was highly intelligent, even for a deity.

He wanders the Freljord during the winter, bringing the blizzards and the death they might bring.

The Heart of The Cold
Day 17

This random storm just came up out of nowhere, and doesn't seem to be stopping anytime soon. Before long, the town is going to freeze to death. I'm going to evacuate everyone to the main hall.

Day 20

We saw something in the blizzard. Something tall and covered in white hair. It's eyes were red. It's just walking around the town, somehow sustaining the blizzard. I think it's keeping us here for some reason. We just need to find out why.

Day 27

It spoke. The demon spoke. It said something like, "So cold... My belly... hurts... So hungry". We have an idea on what it wants. Now to make a plan to satisfy it.

Day 29

We have a plan. The strongest warriors are going to load up a feast of warm gammon, ham, and beef, and... let the thing in the next time it comes around. We hope this will sate it, and it'll leave.

Day 30

We let it, no, "him" in. It stopped at the table, and pointed at its seat. We nodded, and he sat down. Pulling a large piece of gammon, he started to eat, quite rapidly in fact. He fleshed the gammon in only a few minutes, reducing it to bone. He quickly ate his share, about 10 pounds of gammon, an untold amount of hot drinks, and many, many pounds of sweetmeat. He

Day 31

The blizzard's gone. We're safe. All of our livestock survived, and we even found a pack of expertly preserved monster meat. We also found a ring of markings around the town, seemingly thanking us for the feast. We can still see it
