A/N
So this story is going through some rewriting as I look to complete it. Some of the grammar has been edited as well as the spelling…
The land is barren, full of rivers of lava and flame. Creatures of fire walk above the flames listlessly, waiting for orders. The rivers fed a torrent of lava, creating a type of waterfall that cascaded lava into a dark abyss. The ceiling overhead was seamless, heading both directions with no end. Only three mortals had entered this place and lived: Slade, Robin, and Raven. This was the domain of Trigon, the incarnation of evil. The lava flowed over the edge of the falls, falling and falling. When the fall began to seem endless, the lava reached the bottom and splashed into a large pool. From there the lava flowed beneath the rocks toward some lower cavern. A door stands alone on the rock protrusion, leading into a dark hallway.
Candlelight flickers along the empty hallway, illuminating the flecks of mica and quartz, giving the impression that the hallway was the night sky on a cloudless night. The air is still and silent. Nothing living moves in the hall. The air is warm, almost stuffy; yet would freeze the mortal soul. The hall is but one of many, all leading to the same place: Trigon's lair. The hall continues for almost a mile before a door is reached, an obsidian door that reaches above the candlelight into blackness. No door handles are visible, nor any cracks in the door. The heat increases to burning. The door itself is too hot to touch. On the other side is a large cavern.
The cavern is littered with pools of lava and volcanic rock outbursts. The ceiling of the cavern glitters with the light from the fiery glow, showing stalagmites of obsidian. An empty throne lies at the far end of the cavern, facing the numerous doorways. Despite the lack of physical entities in the room, a malevolent spirit lingers, hating the one who weakened it and biding its time. The weak spirit is Trigon, or what remains of him. After Raven defeated her father and sent him back to his own dimension, Trigon began to gather his strength once more, but not a physical form. His form against Raven was destroyed; he was waiting now till an adequate one came through the interdimensional rift to Earth.
Many had passed through the rift, but none would be able to cope with his power, but there was one who could. Trigon had sired two daughters, Raven and Phoenix; the latter the older of the two.
Phoenix had been born seventy years before Raven. She shared no other physical traits in common with Raven other than slenderness. Phoenix was taller than Raven, with dark skin from her mother and pale, ivory hair. She was commonly found wearing black leggings, knee-high black leather boots, and a short halter-top that covered her chest and nothing else. Her long hair was pulled into numerous small braids on her scalp, out of the way during battle. Her eyes were a startling shade of gold flecked with silver and slit-like pupils, almost feline despite her name. Her powers were similar to Raven's, but were not embodied by dark energy; instead they were silver with red streaks. Phoenix's personality was also similar to Raven's, dark and secretive, but she was more liable to get emotional during stressful situations or heated battle.
Phoenix was the one Trigon waited for, and his wait would not be long; Phoenix was soon to enter the rift. His return was near; he strains with anticipation, and makes the necessary plans to destroy Earth and Raven.
