Layer 113 of the Abyss, Orcus' home plane
Thanatos is the 113th layer of the abyss. It is a cold layer of ice, thin air, and dreary moonlit sky. It belongs as much to the undead as the demons - it has the 'minor negative-dominant' trait. Tombstones of every imaginable and unimaginable type dot the landscape, sometimes alone, sometimes ranged as in a cemetary. Undead range everywhere.
