So after i read a topic about the forsworn i instantly remeberd they helmet,you guys probaly know,that their helmet is a skull of a dead elk.Then i rememberd Hircine,when he chooses a form too show himself to the mortals he also choses the same helmet.Let's not forget that one of Hircine' symbols is of an elk.Now let's compare they apperance:
Hircine's:

By watching those images i noted a similarity in booth Hircine's and the "Forsworn leaders" apperance,booth in armor,helmet and command.Why did i said command?simple.As wee can see Hircine commands Werewolfs at his hunt grounds(could alo the forsworn camp represents the same?).Could the forsworn with helmets represent's hircine(commander) and the forsworn normal soldiers, the "werewolfs"?let's not forget the forsworn way to atack,"ambushes" with packs.Like wolfs,werewolfs(and hunters).Is this a coincidence?or they really worship Hircine's?Or i might be wrong?

You can see the link in one other thing as well. The hagravens tend to be good buddies with the Forsworn, and hagravens seem to be creations of the Prince of the hunt (Not sure about that one, correct me if I'm wrong).

This is getting intersting.Also,did Hircine create other species that are not werewolfs?

He's the father of all manbeasts, so he created werebears, werelions, werevultures and other mutants.

Wait wait,Could the Argonians and the Khajiit be his creations too?

Argonians' and khajiits origins seem to circle around Lorkhan and the Divines, so they aren't creations of Hircine.

I can confirm.Looks like Hargreven's could be his creation.But TES:wikia confirms that they worship hircine's:
"On a side note, the witches of the Glenmoril Wyrd Coven of High Rock are known to be worshippers of Hircine, and they will often perform a summoning for anyone that can pay their price. The witches are also able to cure anyone of Lycanthropy an ability that is alluded to in the book."

Also the Hargreven's connection to the forsworn could make my question even more obvious.

I believe its possible, and most signs point to them having some sort of connection to Hircine.

I figured it out at the Glenmoril cave which have same kind of bone-things you can see at Forsworn places. Also the Glenmoril witches who are servants of Hircine have hagraven-type bodies and as far as I know hagravens are priest-like creatures among the Forsworn. And now you have mentioned the thing about the helmets so I think it's quite clear for me now.

can you describe those bone-things?It could probaly be trophies.Hircine love's trophies.

I mean some kind of statues made by deer bones and skins and other things like goat heads on pikes. All Forsworn camps are filled with them and so is Glenmoril cave.
