This article contains plot details from the latest book.
Lumenaria is an elvin fortress built on an island. It serves as the meeting place for the six intelligent species with treaties, especially for events such as the Peace Summit, and also the prison for diplomatic prisoners, people who hold too much value to be imprisoned in Exile.
Lumenaria was built out of lumenite so that it would not be able to burn, even with Everblaze. The walls are intentionally ambiguous to ensure that no one can find their way through unless they have been trained.
Visitors to the cells have to be first patted down to make sure they did not carry with them any weapons, gadgets or jewelry. They are blindfolded and escorted by goblin guards down a stone spiral staircase and several hallways to the dungeon where the prisoners are held.
The dungeon has six arched silver doors lining the room, with no visible locks or handles. To open a door, one has to place their palms on the door to make a combination panel appear so that they could key in the code. The codes change three times a day and are passed along to the Councillors in a random order to make it impossible to predict the person with access at any given moment.
The prisoner will not be able to get close to the visitor as the visitor will be enclosed in a force field that will shift as they move. Every prison cell has a waist-high stone pillar with a silver sword trapped permanently in the stone. The prison cell is set to an extremely low temperature. The prisoner is brought a pillow to sleep, but never at the same time, to mess up their internal clock so that they have an illusion of time.
For the Peace Summit, the attendees stayed in rooms in the underground quarters, luxurious and secured with two locks.
