Elder Scrolls Online dev blog floating around the game's official website. It's all about flame atronachs and how the dev team at ZeniMax is going about creating them.
"Comfortable in both melee and at range, the flame atronach can lob deadly balls of fire, and it radiates a continuous burning aura, making it quite dangerous at any distance," the dev blog explains. There's a bit more verbiage about the creature's sound design as well some screenshots, concept art, and a quick in-game video. You can see this last bit after the cut.
