Dungeons

Kieran stood up and walked to the center of the room, looking at the shackles around his wrists. These will be a problem, he thought, then pushed it from his mind. Now was not the time to think too much. The guards seemed to be changing shifts or something, since he couldn't see them. Now was his only chance.
He closed his eyes and concentrated. Everything began to shift and warp about him as his body took on a different form. His jaw split and poured blood as he shifted dragon's teeth into his mouth. With one quick snap, he bit through the one shackle on his left wrist as it began to shift and change to help the metal break. Then he shifted the other one, snapping it off as well. Both twisted chunks of metal clattered on the floor.
Bones jutted from his back, grew flesh, then scales. Wings sprouted. A tail appeared. Claws extended. His whole body multiplied in size. This was the slow way, but the only way. He needed to work to get the collar off.
He shifted his throat and stomach, forming a breath of fire inside. Shoving his face against the glassy floor, he breathed a massive breath of flame. Even though he shut his eyes tight, it still burned, especially over the empty socket. But the collar was loosening. He did it again and again, rubbing the collar against the ground. It creaked and split, and his neck and head caught up with the rest of the shift.
Finally a full dragon, he turned to Adrian, bringing his head down so Kieran could climb on to sit on his back.

Kieran eyed him with a worried look, then maneuvered his head around the cramped cell to see how Lorcan was getting on. His ears were pricked to pick up any footsteps or other unwanted sounds. Soon enough they would be making a lot of noise.

Kieran growled lowly and then looked up at the vent. Bunching himself up like a coiled spring, he suddenly leaped up, slamming all his weight into the ceiling. There was a loud boom, and the rocks split apart. He dug his claws in and started to dig.

Kieran shoved his forefoot into the depths of the fissure and pulled down a massive chunk of rock, exposing the air shaft more fully. It led up and up. He couldn't see any sort of light at the end. But sure enough, the guards burst into the prison at the sounds. When they saw what was happening, the ones that could shifted into dragons and blew fire and ice and poison at all three of them.

Kieran turned his head around and shot a fireball at the dragons. It passed harmlessly through the bars to knock into the poison dragon. It screeched and flailed around, the smell of burnt metal in the air. The fire one shot another wave of flame at Lorcan. The non-dragon guards had unlocked the doors, and the ice dragon slipped into Kieran's cell, shooting a spike of ice at him.
Just a little farther, Kieran thought. Ignoring the dragons completely, he coiled back and slammed his body against the ceiling. A chunk of rock broke loose, and he crawled into the shaft.

ADRIAN! Kieran shrieked when he felt his brother fall. But the other dragon had fired again, and Kieran had no choice but to focus on defending himself. He opened wide and clapped his jaws around the other dragon's mouth. The ice dragon snarled, lashing his tail fiercely. The dragon shot a blast of ice into Kieran's throat, quenching his fire.
Kieran bit down hard as he could and whipped his head away, ripping off a good chunk of the dragon's face. The ice dragon dropped back down, battered away by Lorcan's tail. Kieran shot up the shaft, Lorcan behind him. He slammed through rock after rock, making the tunnel wider and heading closer to the source of the wind.

Kieran finally saw it, a pinprick of light. He climbed up faster, twisting around like a corkscrew as he crushed the rock away. The passage was getting narrower and narrower. He shifted his wings away to stop them from getting beaten up any further.
