Aurus (orr-us)

Should you find yourself lost in shifting white snows of Bifrost, you may look up into the sky. Far from the city lights, the night sky is an endless sea of stars. But on this particular night, you might think yourself blessed to a gorgeous shifting mass of lights. Until they swallow you whole.
The auroroa of the North Guardian of the Bifrost Neutral and ferocious
Aurus is described by the natives to be a long creature with many legs. No wings to fly, and yet still glides effortlessly through the night sky. Its glimmering surface shines bright in blues, greens, purples, and silver. A tail trails off into a transparent long fin, but its head is massive with layered rows of teeth inside a miasmic maw.
This Demi God is thought to be the only source of warmth in all the Bifrost. Clearly the creator of fire, as it often drops down into Jer'on to gaze into their ever-burning bonfire. All the citizens know to hide when they see it shining in the night, for in the past the beast has gobbled up any strays or foolish warriors that challenge it.
