Thulgrim is a sturdy figure with a long russet beard that is braided with bronze rings, each engraved with a different rune. His hands are calloused, a testament to years of blacksmithing. Despite his stout build, his movements are surprisingly light, almost graceful. He wears a simple leather apron over chainmail, forever dusted with soot. His eyes are sharp and glint like molten metal, always assessing and calculating.
