Dudael
Dudael is the place of imprisonment for Azazel, cohort of Samyaza. It is described in the Book of Enoch chapter 10 verses 4–7:
Dudael is also implied to be the prison of all the fallen angels, especially the evil Watchers, the entrance of which is located to the east of Jerusalem. The way this place is described, Dudael is sometimes considered as a region of the underworld, comparable to Tartarus or Gehenna.
