I joined an all-female barbarian cosplay group.  We're called "The Horde". 

My character is a priestess, and of course I just had to have some light-up elements in my costume.  At the same time I also really want to keep the whole costume within the Horde's costume guidelines, which means everything needs to look ancient and weathered -- rather like I stole it from a defeated warrior after an epic battle.

This project attempts to melt the newest fanciest tech I can get my hands on with the most ancient stories and legends I've ever heard.

Electronics Materials

For the case:

• 3d printer
• Acetone
• Metallic Acrylic paints
