The Thundaga Trinket is a thin, black bracelet with five silver ornaments on it. The central and largest of these ornaments is black and shaped like an eight-pointed star with two small, silver lightning bolts on it. The two outer ornaments are slightly smaller and decorated with both zig-zagging and straight black lines. The remaining two ornaments are small, featureless rings.
