Now standing in ruins, the fortress city of Breth'Nul was built as the capital of the Hakarren Empire by Emperor Zagush I to celebrate the dominance of Orien by the Empire, after the subjugation of the Cyclops was complete.

In its abandoned state, Breth'Nul is not lived in by the descendants of the Hakarren, the Specter, but there are some people and creatures who have made the city their temporary home. There are also some mysteries to be solved and secrets to be discovered, left there by the ancient people who once lived in the city.
