Jötunheim was cold. Snow melted and boiled away the moment it touched his skin, but the wind still ripped through him, violent shivers starting not long after the portal closed and the blistering heat of Muspelheim vanished. The snow melted and boiled under his feet, but the frigid air kept it from staying warm and he had to start moving before he was frozen in ice. Sigyn conjured a thick fur cloak and lined clothing, forgoing the customs of his people of wearing very little clothing. It helped some, but that wind...
The cold was like knives, piercing his skin with such ferocity that he was surprised that he didn't start bleeding from it. The glow of his markings started to dim as his core body temperature started to plummet. Cold could kill an Eldjötun just as easily as any blade, only slower, more agonizing. They needed heat, warmth, the same way a Jötun needed the cold.
His father's political connections couldn't help him, somehow get his banishment lifted, it was their fault he was banished in the first place. Still cursing Eldjötun politics, he trudged through the snow, the cold seeping through the thick boots and starting to penetrate his skin.
The snow storm he walked through only seemed to get worse the further he went, going on memory to where he thought the nearest Jötun settlement was. Maybe a guard there would grant him a quick death, instead of a slow one by freezing.
The cold leeched all his energy from him and it was getting harder and harder to move through the snow and wind, his hand raised to protect his face from the blowing snow as the wind suddenly shifted, hitting him head on and making him falter. Falling to his knees, he curled in on himself, his teeth chattering so hard his jaw hurt, the racking shivers making every muscle scream. Closing his eyes tight, he tried to surround himself in an aura of flames. Something, anything, to stay warm. Nothing happened and he hugged himself, rocking back and forth in the snow as he pulled the cloak tighter around his frame in a fruitless attempt to block out the wind. The ground came closer, the snow barely melting as it touched his skin and he didn't even feel the flakes start to gather as he lost consciousness.
