Generate for me a dangerous scene inside a cave cavern with a river, glaes, and pillars.
assistant
A river of molten glaes rolls bubbling and spitting across most of the chamber's floor. Black pillars rise up out of the magma, their silhouettes crooked and forbidding. Rockets of fiery shards are sent ricocheting off the cavern's walls, launched by explosions from the river's depths. They leave smoking trailers hanging in the air in their wake.
