I guess he was gathering Aether crystals too? Or the Nidhogg eyes are enough for that because have the amount of aether necessary for summon. Who knows.
If one eye was enough to break through a 'certain shield' and two were enough to transform a man into a Primal (who was powerful enough to warp reality in some way), I think it's safe to assume the eyes provide enough aether that matches an enormous amount of crystals that Beastmen wish that could have. All that's left is the worship of those praying to Rhalgr.
