Death's Domain was the home of Death. It was an extra-dimensional realm and has a house and garden.

Death's house has infinite space inside. The rooms include the Life-Timer room,the home of the life hourglasses which keep on running. Then there is the Library where everybody's biography is being written down by itself. The whole house looks old.

Everything in his garden is a copy of everything he has seen in another place because Death can't create, only copy. In Soul Music, there is a swing in the garden for Susan's pleasure.
