As the light above flickered, horns sounded from the besiegers, and huge catapults ignited and unlimbered, unleashing their missiles on the trading post. There were only three of the catapults, but they fired burning bales soaked in pitch. One of the bales fell short, the second had the correct range but drifted to the right as it flew, a burning comet that splattered outside the northern gate.

The third bore down on them like a newborn sun.

Jodah cursed and rummaged through his mind like an artificer rooting through his tool box. He came up with the correct spell in less than a second, but the pale of burning pitch was less than a hundred feet above them, coming straight down.

Jodah unleashed the spell, and the bale struck a hemisphere of pure magical force that rose from the fort, batting it away.
