He picked up a stone and threw it at the demon. 'Go back to the Core where you belong!' he cried. 'Go back and die!'

Ashamed of himself, of his cowardice, Arlen came to his feet and met the demon's eyes. He screamed, a primal cry from deep within him that rejected everything the coreling was and everything it represented.

The demon barely seemed to feel the stone bounce off its armour, but its rage multiplied as it tore at the wards, unable to get through. Arlen called the demon every foul and pathetic thing in his somewhat limited vocabulary, clawing at the ground for anything he could throw.

When he ran out of stones, he began jumping up and down, waving his arms, screaming his defiance.

Then he slipped, and stepped on a ward.

Time seemed to freeze in the long, silent moment shared by Arlen and the giant demon, the enormity of what had just happened slowly dawning on them. When they moved, they moved as one, Arlen whipping out his etching stick and diving for the ward even as the demon swiped a massive, clawed hand at him.

His mind racing, Arlen assessed the damage in an instant, a single line of the sigil was marred. Even as he repaired the ward with a slash of the tool, he knew he was too late. The claws had begun to cut into his flesh.

But then the magic took effect once more, and the demon was hurled back, screaming in agony. Arlen, too, screamed in pain, rolling over and pulling the claws from his back; hurling them away before he could realize what had happened.

He saw it then, lying in the circle, twitching and smoking: the demon's arm.

Arlen looked at the severed limb in shock, turning to see the demon roaring and thrashing about, savaging any demon foolish enough to come within its reach; savaging with one arm.

He looked at the arm, its end neatly severed and cauterized, oozing a foul smoke. With more bravery than he felt, Arlen picked the massive thing up and tried to hurl it from the circle, but the wards made a two-way barrier. The stuff of corelings could no more pass out than in. The arm bounced off the wards and landed back at Arlen's feet.

Then the pain set in. Arlen touched the wounds along his back, and his hands came away wet with blood. Sickened, his strength ebbed and he fell to his knees, weeping for the pain, weeping for fear of moving and scuffing another ward, and weeping, most of all, for his mam. He understood now the pain she had felt that night.

Arlen spent the rest of the night cowering in fright. He could hear the demons circling, waiting, hoping for an error that would allow them access. Even if sleep had been possible, he would not have dared attempt it, lest a shift in his slumber grant the corelings their wish.

Dawn seemed to take years to come. Arlen looked up at the sky often that night, but each time he saw only the giant, crippled rock demon, clutching its caked and ichorous wound as it stalked the circle, hatred in its eyes.

After an eternity, a hint of red tinged the horizon, followed by orange, yellow, and then a glorious white. The other corelings slipped back down to the Core before the yellow touched the sky, but the giant waited until the last, its rows of teeth bared as it hissed at him.

But even the one-armed rock demon's hatred was no match for its fear of the sun. As the last shadows scurried away, its massive horned head sank beneath the ground. Arlen straightened and stepped from the circle, wincing in pain. His back was on fire. The wounds had stopped bleeding in the night, but he felt them tear open once more as he stretched.

The thought led his eyes back to the clawed forearm lying next to him. It was like a tree trunk, covered in hard, cold plates. Arlen picked the heavy thing up and held it before him.

Got a trophy, at least, he thought, making an effort to be brave even though the sight of his blood on the black talons sent a shudder through him.

Just then, a ray of light reached him, the sun finally more above the horizon than below. The demon's limb began to sizzle and smoke, popping like a wet log thrown on a fire. In a moment, it burst into flame, and Arlen dropped it in fright. He watched, fascinated, as it flared brighter and brighter, the sun's light bearing down upon it until there was naught left but a thin, charred remain. He stepped over and gingerly nudged it with his toe, collapsing it into dust.

Arlen found a branch to use as a walking stick as he trudged on. He understood how lucky he was. And how stupid. Soil wards were untrustworthy. Even Ragen said that. What would he have done if the wind had marred them, as his father threatened?

Creator, what if it had rained?

How many nights could he survive? Arlen had no idea what lay over the next hill, no reason to think that there was anyone between here and the Free Cities, which, by all accounts, were weeks away.

He felt tears welling in his eyes. Brutally, he wiped them off, growling in defiance. Giving in to fear was his father's solution to problems, and Arlen already knew it didn't work.

'I'm not afraid!' he cried out to the sunlit world. 'I'm not!'

Arlen pressed on, knowing the lie for what it was.

Around midday, he came to a rocky stream. The water was cold and clear, and he bent to drink. The move sent lances of pain through his back.

He had done nothing for the wounds. It wasn't as if he could stitch them closed as Coline might. He thought of his mother, and how when he would come home with cuts or scrapes, the first thing she did was wash them out.

He stripped off his shirt, finding the back torn and soaked through with blood, now crusted and hard. He dunked the shirt and watched as soil and blood washed downstream. He laid his clothes out on the rocks to dry, and lowered himself into the cold water.

The chill made him wince, but it soon numbed the pain in his back. He scrubbed as best he could, gently washing out the stinging wounds until he could stand it no more. Shivering, he climbed from the stream and lay on the rocks by his clothes.

He awoke some time later with a start. Cursing, he saw that the sun had moved far across the sky, and that the day was nearly done. He could travel a little further, but he knew the risk would be a foolish one. Better to spend the extra time on his defences.

Not far from the stream was a wide area of moist soil, and the sod pulled free easily, clearing him a space. He tamped down the loose dirt, smoothed it, and set to warding. He drew a wider circle this time, and then, after checking it thrice, drew another concentric ring within the first for added safety. The moist earth would resist the wind, and the sky showed no threat of rain.

Satisfied, Arlen dug a pit and gathered dry twigs, building a small fire. He sat in the centre of the inner circle as the sun dipped, trying to ignore his hunger. He doused the fire as the red sky grew lavender, then purple, breathing deeply to steady his pounding heart. At last, the light vanished and the corelings rose.

Arlen held his breath, waiting. Finally, a flame demon caught his scent, and raced at him with a shriek. In that moment, the terror of the previous night came rushing back to him, and Arlen felt his blood go cold.

The corelings were oblivious to his wards until they were upon them. With the first flare of magic, Arlen breathed his relief. The demons clawed at the barrier, but they could not pass.

A wind demon, flying up high where the wards were weak, passed the first ring, but it smashed into the second as it swooped down at him, landing hard in the space between. Arlen struggled to maintain his calm as it lurched to its feet.

It was bipedal, with a long, thin body, and spindly limbs that ended in six-inch hooked claws. The undersides of its arms and the outsides of its legs were webbed with a thin, leathery membrane, supported by flexible bones jutting from the creature's sides. Barely taller than an adult man, the demon's spread wings spanned twice its height, making it seem huge in the sky. A curving horn grew from its head, bent back and webbed like its limbs to form a ridge down its back. Its long snout held rows of inch long teeth, yellow in the moonlight.
