New Freljord Champion Speculations

So we all know now that the new champ is related to this image:

a nordic horn. and so it seems quite logical to expect a champ from Freljord.

So i still hope it might be a Watcher etc. here are some related pics:

But they obviously dont blow horns.

So here is my specualtion: It could be something/one to an Einherjar. This "creatures"/humans are mythic soldiers which are, somehow, related to the WILD HUNT. So they blew horns in their battles and prepare for Ragnarök.

Some excerpt: >> Noble Viking warriors aspired to become one of the einherjar after they died.

The lifestyle of the einherjar would have been the envy of living Vikings. All day long, they fight one another, doing countless valorous deeds along the way. But every evening, all their wounds are healed, and they are restored to full health. <<

Here are some pics to get an idea:
