Pyre of the Fallen,The fire within us all

• - Risen from the ashes of those who has come and past, strengthen by will and the determination of everyone who has and has not yet fallen - the mighty Phoenix is reborn time and time again. They say you end your life upon a final pyre, as you realize your sprawl back to nature, but you also begin your life stood before a Pyre as it judges you for redemption, mortality and your worthiness for reincarnation.

• Fire is life, fire is death - and it is the work of the Pyre to navigate before the two.

Brisingr - Old Norse for fire, also the magic word for fire in the Inheritance Cycle books (Eragon)

Tachocline (pronounced tack-o-cline).
From tacho-, a combining form meaning speed, and -cline, meaning slope.
A layer within the Sun that separates two distinct regions of rotational behavior: the radiative zone and the convective zone. In the inner, radiative zone, the Sun's material rotates nearly uniformly at roughly the same speed. In the outer, convective zone, the Sun's material rotates differentially, meaning that different latitudes and depths rotate at different speeds and the equator rotates faster than the poles. The tachocline is a very thin, shear layer in between these zones, where the rotation transitions from one mode to the other. It is thought to play a crucial role in the Sun's magnetic field generation.

Hoping this counts, since the Sun is one gigantic fire ball
