Life-stream

A type of fuel made from liquidized souls.

Because Life-stream cannot be crafted by mortals, it is sold by various death gods and merchant gods.

Among mortals, life-stream is heavily regulated in many countries and cannot be resold once purchased.

Life-stream is composed of liquidized souls.

Life-stream is harvested by death gods via taking the wicked souls who died in their territory and crushing them together until they form a viscous liquid as thick as simple sugar syrup.

Life-stream has no fixed price. Instead, buyers must complete a certain request that the seller makes of them. The more life-stream being sold, the more difficult and/or numerous the requests.

The materials made to create life-stream are abundant, but the process of liquidizing souls is difficult. Paired with the daunting requests gods make for it, it is quite rare.

Life-stream relies on the torment the souls involved suffer through in order to generate intense magic power. Because souls are incredibly durable, this magic power can be recreated many times. This allows a lot of power to be harnessed with minimal life-stream.

Life-stream only uses the souls used to make it.

Because of its potency and re-usability, Life-stream is used as a fuel source for power generators. Notably, a certain inventor used it to power an android.

Life-stream is a glowing blue ooze that looks like melted glass. Some say that you can hear the screams of the tormented souls inside if you lean your ear into it. Not that you would, since it's highly volatile and would burn your ear off.

The most powerful generators that use it usually only burn through an oil barrel's worth every year.

Life stream is a bright cyan color, like a tropical ocean.
