Night golem

Swirling pieces of flickering light flow inside the short black body of a night golem. A hazy white film covers the inky substance, but occasionally a tuft of black essence pushes through, expelling the tiniest pinprick of light. Streaking as it crashes down, it appears to vanish completely just before it impacts the floor. Although the array of flashes warrants quite a sight, the golem's serene beauty is marred by a snarling humanoid face.
