Editing In Nomine (section)

==Essence: Or, "Why is Humanity important?"==
''In Nomine'' has an interesting economy set up with Essence.

* You need Essence in order to do almost anything supernatural.
* Everybody, Human, Celestial, Ethereal, or even Animals, regenerates Essence at some point once a day (notably, for Angels, sunrise, for Demons, at sunset).
** The amount regenerated depends on the "size" of the soul, but it's usually from 5 (for a human) to 18 (for a maxed out unWorded Celestial).
* Humans are weaker, individually, then Demons or Angels (or even most Ethereals), but outnumber Celestials and Ethereals by at least a thousand to one.
* Ordinary, non-Symphonically Aware Humans expend Essence unconsciously.
** This essence is usually sent to whatever the Human considers important, especially things they ''actually'' care about.
* Words are Heaven and Hell's most convenient way of gathering Essence.
** But too much Celestial interference (known as Disturbance) of the wrong kind can prevent Words from gathering Essence in a given place. (Further, anything sufficiently blatant can be "heard" by just about all Celestials and most Ethereals in the area, frequently leading to heavily armed investigation fairly quickly.)

Some thought on the above, with the added caveat that all sides try and keep the War secret, should lead you to be able to conclude what The War mainly consists of.
