A pretty small detail on the Thunderstrike armour that I like and helps sell the fantasy aspect even more is that a lot of the armour plating is held on with straps and belts, whereas previous SCE armour had solid continuous pieces that make it look more like power armour
This rumour engine has the same styling on the stone as Yndrasta too, doesn't look too much like Fimir nor insects like we think the Silent People are, but I could be wrong
