Halfwitch Studios

A true witch has white eyes which cannot see the physical world - only energy - energy they use to cast their spells. Yet as powerful as they are, the blind witches are exploited by the church and made into servants of the archibishop, occupying witch towers which house massive roaring engines to fuel their magic, and sharp-eyed girls to guide their spells. 
But a halfwitch is different - as she still has one good eye which sees the natural world - and this makes her dangerous.
Too dangerous to be left alive.
