It was designed mainly by Nico di Angelo and constructed with help from summoned 'undead' workers.
The cabin walls are made of solid obsidian and a skull is hung over the doorway. There are torches that burn Greek fire twenty-four hours a day. The cabin is windowless.
Inside the cabin, the beds are coffin shaped with polished mahogany frames, brass railings, bloodred velvet pillows and sheets. There is also a small shrine with bones and jewels. When Hazel temporarily stayed in the cabin, she partitioned her side with sheets for privacy. They were presumably taken down when Hazel left.
