The Sunset Knights live in a castle on the Atlantic shard, in the very heart of Britannia. It is located close to Britain. Access to the castle is restricted to guild members. There every Knight pronounce his oath upon joining the guild. Soon the headquarters on the Drachenfels shard will be built as well.
