Erebus

The monstrous Spire Messenger tore apart the gelid wind as it raced across the frigid vastness of the twilight sky. Behind it, a churning wall of dancing snow crawled slowly, devouring the world like a hungry beast. 

There was a gaunt figure kneeling on the back of the flying monster, clutching at its black feathers with an onyx gauntlet.

Sunny did not look back, knowing that Serpent was much faster than the pursuing titan. In that, at least, they held an advantage. 

'It will catch up soon enough, though.'

He was contemplating the results of sacrificing his swarm of thralls. 

None of them had been able to withstand the lethal cold of the Winter Beast's domain for long, which meant that there was no type of resistance that could help Sunny survive there — at least none he could find in a short amount of time. 

The thralls had perished swiftly, sapped of warmth of life. Their bodies fell into the snow, slowly turning into ice sculptures.
