From what I recall, Valind's followers as mentioned are mainly Ice trolls (by way of his alliance with Himile?) and some kind of frost giant. But he does have humanoid warriors, too? Are these mortals, or more like the demigods/lesser divines found somewhere like in Orlanth's hall?
Part of what made me wonder about this was how Valind, unlike most deities, seem to be associated with one terrestrial area (the Glacier/north in general) as opposed to the more otherworldly domains of gods like Orlanth and so on. Don't get me wrong, I know there are hundreds of hills and mountains associated with Orlanth, but the contact with him there depends on ritual times and other factors, whereas the Glacier is sorta... always there?
Admittedly, the easiest answer would be just to say that the Glacier is kind of a Gods Plane/Hero Plane domain the further north you go, or in certain spots, so it's not like you have roving bands of Valindings about in a mundane sense.
