Vortigern

Fortress Vortigern was an immense fortress with an accompanying sea gate known as the Gate of Vortigern. It served to hinder entrance to the Holy Midgand Empire from the narrow northern sea route.

While Vortigern's main function was to prevent the entrance of daemons and other threats to the empire, the Gate unfortunately hindered the efficacy of trade by sea merchants from the north.

Initially said to be impregnable, the fortress is breached by Velvet Crowe and her team when they pass through on their way to Loegres.
