Darkness PD is the main police station that Elliot, Harper and Morrigan are all based at. Darkness itself is a city of four districts, and Elliot works for district 1.
Most of Darkness PD is technologically connected, but Elliot, Harper and Morri have different difficulties with it – Elliot doesn’t like tech, Harper can’t use it due to the fact that he’s a technomage, and Morri is working undercover to expose the corruption in the police itself.
Harper’s status is mostly explained later in the storyline, but technological mages in Darkness itself is a bit of a mystery, which I’ll be talking about in M for Magic – another area where I’ll be talking about all three book types.
