It is egg-shaped (not cubic), covered with funeral veils, with a catafalque at the center and four boxes for the main factions or Houses. It is completely isolated from public view outside. It serves as an arena for duels, executions, and martial and funeral ceremonies. The Senatus Popularis meets here as witnesses and judges.
It was the scene of the combat against the five chromatic dragons and of the funeral ceremony for Zoé.
