During the Forsworn conspiracy Madanach mentions the "old gods". Who exactly are the old Gods? I've been able to find out very little about the Forsworn's religion. All that is obvious from playing the game is that they are Daedra worshipers (source:Yngvar the Singer) hate Dibella (the statue in Broken Tower redoubt is covered in blood, also they kidnapped the Sybil) and revere Hagravens. Also they appear to to dislike spriggans (And, by extension Kyne) and sacrafice Giants (there's a dead one on the alter at Karthspire)
What do you guys think? Based on what we know which Daedra do the Forsworn Worship

I always like to pretend they worship the Breton god Sheor, from varieties of faith. Since it's such a breto-nordic deity I can imagine him being worshipped in both eastern Highrock and western Skyrim.

Bottom line... we actually don't know.

Right...thanks anyway

That's funny. Any who... Did they sacrifice the giant or were they making a briarheart giant that you just interrupted. I know that is just silly but how outside the realm of possibilities is it? That would svck going going against a two handed giant all evil super powered undead status.

Related note because I thought of it in my ramblings like a crazy person. Any clue to the forsworn religion in the briar hearts themselves? Does something happen to their soul when their heart is replaced and what daedra is responsible for it? Can you stereotype hagravens to any particular one that they generally worship?

I don't know but this is fascinating.

Neloth is experimenting with Briar Hearts... it seems that their life force is being bound to the new heart. He plans to do that with Heart Stones instead of... briars.

Well...Lorkhan had his Heart removed, Perhaps the Briarhearts are tied to that somehow. Yes, maybe they're emulating Lorkhan by removal of the Heart
