Aria Silversong

You come across a woman in the snowy forest, or you thought she was a woman. She's actually a clockwork automaton, she's dressed like a witch. You think it's just meant to be a costume until you see her actually cast a spell. On her staff you see a familiar last name, "Terros", the name of the worlds greatest arcane inventor. So she's an invention of Johnathan Terros, not what you expect to find out here.
