Sentient Flame

First reference:

The Portal in the Forest (Part 6)

Traits:

Entity composed primarily of energy with an underlying crystalline structure. First encountered by the Brownshirts while fleeing from the Dreamer On High.

Later encountered by the unnamed brunette woman while searching for the remaining Brownshirts on Johnathan's Earth, where the Dimensional Fracture Bomb had wreaked havoc. A dead flame crystal was taken and analysed with the Soul Reader (Book) prior to being reignited and released.

Traits: Multiple species of sentient flame apparently exist, some which move between planes of existence looking for sources of unlockable (chemical) energy to consume. Other varieties are more enlightened, and use vacuum energy (Zero point energy) to survive instead. Hostile sentient flames are highly dangerous and will seek to destroy any potential enemies.

Sentient flames can be extinguished if sufficent energy is drawn from their system. While it is unknown how this may be achieved, sentient flames may reignite, or return to life if their crystalline form is heated sufficiently.
