I'm doing a project that I'm basing on Celtic mythology, but very very loosely interpreted. Kind of reading it as if it was science fiction instead of mythology in places. So this is one of the Tuatha De Danann tribe crossing the ocean on the way to invade Ireland. He's got a smoke cloak that he can pull over himself, this is how he looks in battle, but they would actually pull it over themselves and travel as a cloud usually, but that wouldn't make for quite as interesting concept art. So the Fomorians stood on the shore just see this black fog rolling in and then they throw back the cloaks and battle begins.
