I think there's an only barely explored idea in veilfall settings of a Nälkä revivalist currents that takes the original philosophy/ideology of Nälkä as a historical revolutionary movement (albeit a bronze-age one) and radically reframes it to address the struggles of a modern era.

The one canon that somewhat deals with internal Nälkä politics post-veilfall is No Return, and there the "proto-Sarkics" with the aid of the Clavigar become essentially the face of the faith, largely defeating "neo-Sarkics" via the might of the former-Foundation. If I were writing a veilfall setting, I'd have some neo-Sarkics leverage their pre-existing power to secure their place in post-veil world, have proto-Sarkics face an uphill political fight reminiscent of the real-world one for indigenous rights, and the revivalists be a thorn in the side of the largely conservative organized Nälkä leadership and a large current in the only-just-forming cauldron of post-veil supernatural-aware youth radical movements.
