Promises is a piece of fiction for Archbliss: The City of the Sorcerers, one of the supplements for Cities of Sundara, which is available in versions for 5th Edition and Pathfinder.
Kadar panted, sucking air into his burning lungs. The air was hot and thin, and it made his head spin. He closed his eyes, pressing his cheek to the stone floor. It was incongruously cool, and it helped stop the world from pitching and yawing behind his eyes.
“Again,” Soria said through the grate in the wall.
Kadar bristled, clenching his teeth. He had been in the black cell for weeks, now, and he had done everything asked of him. The walls had glowed, and he’d unleashed everything he had until the fires had burned down to embers. He slept, he ate and he trained, but it never seemed enough.
“Again,” Soria repeated, lowering the grate once more.
Letting out a wordless cry, Kadar exploded in flames. They rose higher and higher, slamming against the ceiling and licking down the walls. The veins within the cell burned bright, sucking in the fire, until there was nothing but a slightly charred smell on the air. Kadar collapsed bonelessly, shivering in every limb.
“Good,” Soria said, the single word of praise more than she usually offered. “You’re almost ready, now.”
Kadar wanted to believe her. He wanted to believe that soon Soria would open that door, and guide him out into the city where he could meet others like himself. Where he could finally breathe the cool, open air, and feel the sun on his face again. As the light faded from the walls, and he heard Soria’s steps whisper down the hall, Kadar closed his eyes.
He wanted to believe they’d let him out. He wanted to believe the promises were true. But deep down, he didn’t. Not anymore.
