Fjordsgate Citadel

Establishing shot of the citadel in a barren tundra infested by witches.

Gates and defence towers using holy water are built in an attempt to stem the infiltration of the Coven and their thralls, who's blood magic grows stronger with the capture or conversion of citizens and their children.
Split into three levels, the lower 'Midden', the Mid-Town and the Eagles Nest, the monastery that sits atop of the geyser the citadel is built upon is responsible for the yearly Purge of witches from the city by unleashing a torrent of holy water from beneath the ground.
