The World & History

Overview
It is stated that this world in which Lucifer built is not an afterlife, but an entirely new creation with flora, fauna, and demons of all shapes and sizes. The city of Centralia, residing in the middle of continent, is the most modern in terms of technological advances. The rest of the outer-lying lands contain older castle architecture.

Demons
Demons have a lifespan around one-thousand years, and range significantly in terms of abilities and physical looks. Demons who have pure blood (ie blood from only their species/race, not mixed) have greater physical strength and maybe even special powers and abilities.
 * Trivia: All demons have pointed ears. Most demons are left handed.

Angels
Angels are immortal and do not age, though they can die from bodily harm as shown in flashbacks of the war. They practice enochian magic (old magic of Angels). Angels appear to hate wearing garments, and even in the war fought without armour.
