The citizens of Ba Sing Se went about their usual routine. The Dai Li were strangely absent from their usual patrols today, but the citizens didn't bother wondering why. Better to assume they were always watching you, lest you disappear in the middle of the night.
Suddenly, screams began to ring the air. One woman was shakily pointing a finger to Lake Laogai, showing a sight that should have been impossible.
Lake Laogai water's...had caught on fire.
Deep beneath the fire infused waters, the Dai Li were in pieces, some rather literally. Blood and viscera decorated every corner of the halls of the secret base. Some members of the Dai Li found themselves in a room, trying to hide behind their prisoners. A black silhouette of a man, illuminated by an eerie red glow, began to approach. One brave (or foolish, depending on one's view) Dai Li agent decided to run up and attack the man, encasing his fists with earth. He winded up a punch with his right arm and started to follow through, only to find his arm caught in a vice grip. The man slowly started to twist the Dai Li agent's arm counterclockwise. The agent cried out in pain, forced to release his makeshift gauntlets, then looked up in pure horror at the man's face. The red glow shifted, somehow into the agent's chest, and the agent fell to the ground, like a puppet whose strings were freshly cut. The remaining Dai Li bought out two Joo Dees from the room, holding them with a piece of earth shaped into a knife.
"Enough! I've had enough of this! You leave us be, or this woman's death will be on your hands!"
The man chuckled, his cold voice chilling the air. The red glow of his weapon still present "Hostages only work if your enemy cares if they live"
The Dai Li started shaking in terror. Who was this monster?! Suddenly, their breathing started to seize. To their horror, they started levitating, releasing their hostages. The men fruitlessly clawed at their throats, desperately trying to breath. "Not that it'll matter to you both.", the monster stated, before closing his fists. A loud SNAP of bone was heard, as the Dai Li's necks were crushed telepathically. With the last of the stragglers picked off, the man headed to his main target. His target was behind the heavy doors, reinforced with Earth and Metal. He snarled. Feng would pay for torturing Toph like that, forcing her to give up her most precious technique just so the pain would end. He reached out with his power, calling on his endless hatred of the man that dared to hide from his fury.
SMASH
The doors were blown to smithereens, along with the Dai Li trying to fruitlessly reinforce it against the intruder. A terrible roaring of metal, earth, blood, and bone mixed into a horrible cacophony. Long Feng was blown away by the extreme power that had been thrown into the last line of defence he had. Everything had gone to hell for the man. His remaining Dai Li were either dead, or close to dying. His legs were broken, and as he pitifully crawled away from the raging maelstrom that had destroyed his base, he felt himself getting dragged by his legs. He screamed in terror, desperately clawing the floor in an effort to get away from the monster dragging him. It didn't work. He was thrown harshly towards the door that had just been broken.
Blood red eyes glared hatefully at him, accentuated by a horrific burn scar that carried across his face. The monster started walking up to him, chuckling darkly.
"I told you, Feng. I told you, the day I found out what you did to the woman I cared for, that everything you cared for, I would destroy. Your city, your people, your power. All of it, I would burn to ash." The monster knelt down to Long Feng's level. He grabbed Feng's chin, forcefully.
Long Feng, desperate, tried to speak to the monster "Your...your….friend...the...Avatar" every word was spoken with excruciating pain. "He...he...would...not...approve."
The monster shook his head "Aang is a little indisposed at the moment, thanks to you. Besides, even if he was awake, I doubt he'd be able to reach here that quickly."
Feng was shaking in terror. "I...I...have...information…on...your…"
"Sister?" The monster chuckled. "I've known about her since the day she entered this city. Face it, Feng. You have nothing. Nothing to offer me, nothing to give to my companions. So do me and the world a favor, and die." Fire started to dance around the monster's body.
Feng screamed.
