Isolfr

Isolfr is a dragon infused with ice. Nobody knows how this happen, and he'll surely snap your neck if you pester him about it. The skeletal, ribcage-like structure upon his chest is part ice and extremely fragile. He doesn't like to stay out in the sun because of this, not wanting to risk parts of his internal organs melting.
The odd thing isn't just Isoflr's glacial traits, he can also twist his neck all the way around; like an owl might. Meaning, if you're behind him, he will swivel his head around three-sixty degrees to meet your gaze. His bright green eyes with faint pupils are like looking into an untamed gust of wind, always swirling with inner rage.

Isoflr, affectionately nicknamed Iso by his friend Haust, is an indifferent dragon. He doesn't like the term 'cold' or 'cold-hearted', because he absolutely loathes when other dragons speak of his glacial oddities and will jab you with his spear.

Iso may seem all frigid and uncaring on the outside, but he's as warm as the Flamecaller's domain on the inside. Nobody knows why he keeps these inner feelings locked away, or why the subject of being partially infused with ice is so touchy to him, but many believe Haust will figure it out.

Haust is the only dragon who can get through to Iso.
Because of this, the burning banescale now knows that this unmoved dragon of ice has repeating night terrors when he's trying to get sleep. He'll wake up sweating uncontrollably, for no reason, wanting to scream his vocal chords out.
