This is Void Spirit, a character from Dota 2. I had the figure sculpted by "felix_3dart" on Fiverr as part of a video on my youtube channel, Miniac. I do not own the creative rights to Void Spirit, or any property inside Valve's Dota 2. I am not selling this STL nor should you. This was simply a fan project.
