Dragon Age: Redemption, a six-episode web series in which she plays Tallis, a sarcastic elf assassin. Uh, that is to say, she's a sarcastic elf and an assassin -- otherwise she'd have to stab herself immediately.
Day reveals that there's no danger of that happening by accident, as she spent several months training with daggers before filming. The enthusiastic star didn't share much in the way of plot or how it connects with Dragon Age 2, but the first trailer (embedded after break) reveals that it won't be all dialogue trees. Based on the brief bit of footage, we can deduce that Tallis' main activities include sprinting through forests, ducking beneath axes and smoldering directly into the camera.
