It's a bit late for this but I decided to do some editing to this story. Those who still read this piece of work, please give me some opinion. I'll be really grateful.

Lief sprinted the length of the corridor.

"I'm an Ol, Lief"

Those words were echoing in his ears as he ran as fast as he could toward the top of the tower. Dain is an Ol. Lief couldn't believe it. He had thought of Dain as one of his best friends. He trusted Dain. And yet, Dain betrayed them all. Their friendship was all a lie from the start.

Lief remembered the day Dain saved them from the Ols. The memory made Lief feel hurt and ashamed. He should never have trusted anyone that easily, especially after having been warned of these shape-shifting monsters. There were ambushes wherever they went, too many of them to have been coincidences. There was obviously a spy who was close enough to them to be able to know their every move. How come he didn't see it before?

One more door and he would have to fight face to face with Dain at last. Lief stopped, took a deep breath and open it. There was his opponent, holding the belt with his knife. Dain no longer wore his friendly expression as he always did. Lief could only sense coldness and cruelty behind those purple eyes. There was absolutely no trace of the boy he knew.

"Give me back the belt!" shouted Lief

"Why should I? You must have known you'll have to fight for it" smirked the Ol, waving the dagger from which the belt was hanging in a mocking motion.

Lief held his sword in front of him, his grip tightened.

"You deceived us!"

"You were just too naïve and stupid. It was so easy to lure you into our trap. Your friends are struggling for their lives and I dare say they don't have much hope. Doom is already down, isn't he?"

Lief felt himselt boiling with anger, at both the traitor in front of him and at himself. They were the reason for his comrades having to fend for their lives at the moment, and if any of them died, their death would be totally in vain, as would their whole journey if he lost here. With a loud cry, he charged in. He attacked the Ol furiously, slashing and stabbing every bit of the enemy his sword could reach, but it looked like he didn't do any damage. At the places the blade struck, the Ol's human skin gave way to some sort of rock-like scale without any sign of having so much as a scratch. The creature was practically standing still for him to hit, his still human face wearing a taunting smirk, his hand still keeping the belt out of Lief's reach. Aiming straight for the Ol's heart, Lief thrust his sword, but just like the rest of the Ol's body, it was like hitting steel. Grinning maniacally, the Ol began his counterattack. Using his now fully mutated arm as a weapon, the Ol made one powerful swipe at Lief and the latter was forced to bring his sword up as a shield. The impact when the hit made contact sent Lief staggering back several step. He jumped in again, but with his attack leaving no damage, this fight was pretty much one-sided with him at the losing end. The Ol switched to a lower aim, targeting Lief's leg. He immediately dodged, but the Ol was just too quick for him. His right leg was grasped and he felt himself being helplessly slammed onto the ground, his sword bounced out of his hand at the fall and landed several steps away. His arm reached out in a desperate attempt to retrieve the weapon, but he hadn't even come close when a cold hand clamped around his neck and slowly lifted him into the air. Lief couldn't breath. He swung his legs wildly, his hands clawing at the Ol's grip without much effect. As his struggling got weaker and weaker, Lief realized the cold truth that he was going to die at this place.

"Is this the end?"

Lief's vision was getting blurry, he was holding onto the Ol's arm with only one hand, the rest of his body going limp when he heard the sound of the door being blasted open. Someone came running in. Out of the corner of his eyes, Lief could see that it was a Grey Guard.

"What are you doing here?" the Ol barked at the new arriver. Clearly the creature hadn't expected their fight to be interrupted in this manner. The Grey Guard stood frozen at the threshold for a moment, seemingly taking in the scene in front of him. What came next was absolutely unexpected for both Lief and the Ol.

The guard unsheathed his sword and came running in. Lief closed his eyes and braced himself for the metal to sink through his body. It never came. Instead, the grip that was strangling him was loosening its hold, and Lief was dropped to the ground. Gasping for breath, what he saw happening sent his head reeling. The Grey Guard was attacking the Ol with all his might, forcing his opponent to release its previous prey to fend off the surprise assault. Spotting his sword, Lief snatched it and made another aim for the Ol's heart but the result was the same as the last ones. He dodged another attack and saw something flying his way. He grasped it by instinct, and only when he held the object securely in his hand did he recognize it. He blinked. It's was the belt. Somehow, in the midst of the battle, the Grey Guard had managed to snatch it from the Ol's grasp, and for some unknown reason, decided to pass it over to him. Taking what could very well be his last chance at victory, Lief, with a lightning-fast motion, tied the belt around the Ol's waist. The effect was immediate.

"No!" screamed the Ol. Its face twisted in pain. Abandoning both of its enemies, it reached for the belt, trying to pry the offending object off his body. Grabbing the opportunity, Lief plunged the sword into the wailing Ol's chest. This time, the sword sunk in and went all the way through.

"Arghhhh!" The Ol was writhing. It pulled out the sword and swung it away, but the damage was done. Its body was starting to quickly disintegrate and its feet had melted into a mud-like liquid. Its hand, however, was slowly changing back into a human hand.

"We could've been friend" pleaded the Ol, holding out his hand. Its face was still that of the boy Lief had called his friend, and now without malice. Looking back at this moment in later years, Lief would still questioned himself just why he fell for it. Now, however, he thought that somehow, Dain had returned. Leaning in closer, Lief held out his own hand.

"Lief! No!" For the first time, the Grey Guard spoke. And it clearly wasn't a Guard's voice. Lief didn't even have time to wonder why that voice sounded too familiar. The hand with which the Ol was holding out transformed again and it made a dash for Lief, who was stunned. He couldn't move. There was no way he could dodge in time. At the very last second, he felt a hand pushing him out of the way. Landing facedown on the ground from the force, Lief quickly turned around and to his astonishment, saw the Grey Guard standing there with the Ol's hand pierced through him. He watched, as if in slow emotion, the rest of the Ol dissolved and the Guard crumpled onto the ground, unmoving, blood pooling around him. Without knowing why, dread filled his chest as he looked at the body in front of him. Scrambling to his feet, Lief rushed to the Guard's side and removed the helmet with trembling hands, then gasped as a familiar face came into view. It was Dain.
