Berne

Berne is the Kingdom of Flame's Region Tyrant. It's Ethr Zone of Residence is the Dark Star, the ball of flames that gives Earth warmth during the night. Only ever returning to Arcerra for sacrifices. The Current form that it takes is called Nuntisol.

Namesake
Region Tyrants get their "true" names from roads I used to live on. Berne Road. Sounds like Burn. Suitable for the Fire Tyrant. I forgot where I got Nuntisol from.

Ethr Zone of Residence
The Dark Star is a giant ball of burning Ethraksha that stays above the part of earth furthest away from the sun, keeping it warm during 6 month long nights. The Dark star has shallow, simple Programming, which makes it an ideal food source for Region Tyrants.

Speaking of which, the other Tyrants of Arcerra are able to feed off of the Dark Star since it becomes within reach to all of them once a year. Or they would, at least, of Berne didn't viciously defend the Ethr Zone as it's own territory.

Appearance of Current Form.
Nuntisol is a Final Fantasy XIV style dragon that burns hyper-hot white and blazing red. It has 12 limbs: It's forelegs and hindlegs obviously, but Nuntisol also boasts eight MASSIVE Seraph-Style wings. It's also massive, but still the second smallest after Rockmount.
