An explosion, that's what he was. The young man pointed his longsword-length staff in the direction of two soldiers and focused. A small distortion appeared over its metal body and collected at the tip. It built up for a fraction of a second before surging toward the men, sending them crashing into the cavern wall and sinking to the ground unconscious.
He sensed someone charging from his left and swung his staff, intercepting a swinging sword and turning its blade into steel dust. The man holding the now-useless hilt gaped at him. He swiftly brought his weapon to the man's head and tapped it, sending enough energy through the staff to knock him out.
He turned to face five other soldiers who were nervously pointing their weapons at him. He paused for a second, staring at them.
"Run," was all he said. The word reverberated throughout the cavern, echoing off the stone walls and settling deep in their bones.
Three immediately turned and ran out. The remaining two, shocked by their companions' behavior, looked at each other uncertainly.
"Hold your ground," an authoritative voice commanded. A man dressed in varying shades of grey stepped into the cavern from a side passage, leading a boy and a girl dressed in ragged clothing and bound in chains. Their eyes were coated in a grey film. "He can't release the full extent of his power while in the cavern; he is too weak to protect himself and the children from a mountain of rubble."
"Isten," the young man's heart sank when he saw that Isten held a tetrahedron the size of a helmet in his hands. It glowed blue, like the purest ice from the arctic. It was an ice vault. Any who could wield it would be able to control the winter elements.
The man walked toward him, gesturing with his head.
"Excuse me," he said.
The young man stepped aside, his eyes blazing with anger. He watched as the children were led to the cavern's exit. Isten turned and faced the young man again and held the conduit of ice over the ground. Ice grew beneath it until it reached the floor. He waited a second before letting go, leaving the vault supported by its ice pillar. Isten looked at the young man with a smirk on his face.
"So," he said as more men loyal to him entered with weapons drawn. "Shall we talk?"
The young man gripped his staff tighter.

It was cold. Jagged shards of ice coated the walls of the cavern and shattered swords and shields lay strewn on the ground. On top of a mound of ice, power escaped through cracks that covered the surface of the severely damaged ice vault. The young man knew he and the children would freeze to death in a matter of minutes. They, unfortunately, could not escape because of a cave-in caused during the conflict.
The children, now free of the grey man's influence, though still showing a light grey film over their eyes and still bound, huddled against one of the walls trying to keep warm. They looked at him with fear and hope, but the young man knew he had no chance of saving them.
He walked to the ice vault, deflecting the beams of ice that shot towards him. He placed his hands on its freezing sides, wincing from the pain.
"Hiram?" the boy whispered.
"I'm sorry," he said, not bothering to hide the sorrow he felt as he filled the ice vault with his power. There was a burst of light and a wave of freezing ice. His stayed conscious long enough to feel his body stiffen and see the terror stricken children become instantly encased in ice, their hands held up in a vain attempt to block the cold. Then his world turned black.
