So I talked about Human religions, then Human religions with non-human origin, and a one for everyone. Now let's review the non-human faiths.

The Orcs - with the exception of one tribe - renounced their ties to Orwella. Instead of her they worship their own Heroes who cheated the Curse of Orwella and retained their souls. They are deified entities but not on the level of gods. They grant powers to Orc shamans tho. Southron Orcs are all belong to Krán and serve Ranagol, and a tribe took Darton as their patron, who turned them white. White white, not pink white.
They were created from many creatures but their closest relatives are Humans and wolves. They are stronger than humans but less spiritual and usually less intelligent. They are carnivores who live short (bout 40 years) but intensive life and live to fight.
Orcish blacksmith and weaponsmith's make good steel as they utilize coal as well but crude items out of it coz no need for pretty ones. Mostly human slaves are working in their iron and coal mines, basically they are worked to death as they have to follow the lifer rhythm of the Orcs who sleep very short periods and active as fuck. No other industry really exist, maybe tanning hides and woodworking, otherwise they hunt their food or plunder it from human settlements. Some tribes keep boar herds and feed them acorns in oak woodland. I dunno how feasible is this. Sounds cool tho.
Orcs are divided into sixteen tribes in the North and unknown number in Krán. The leading tribe is the Seers, the Stormwakers are very good fishermen and pirates, Loyals sacrifice to Orwella and the Taciturns serve Darton.

Goblins are similar, but small, skinny and have many tribes. They worship all kinds of gods but they also have a Hero, called Menegle. Every tribe has different views on him but it's common that he's a "king in the hill" type of champion who will come back later. Some say he has already returned, others try to resurrect him with certain rituals.
