Wyrm of the Laurels… from the Dawn of Magick

Mirian heard the percussion of the great wings before she saw the wyrm. Even in the darkness the brilliant scales shimmered as the massive beast flew against the backdrop of the inferno that was the fortress. One of the Centurions in the rear halted, turned his steed, and hurled a bejeweled javelin toward the dragon.
“That’s futile. No man can hurl a missile that distance,” Mirian commented.
“Watch,” Burun said quietly and knelt down. He tugged on her shoulder, and encouraged his life-mate to crouch as well. Marian’s eyes were fixed on the javelin. The missile left the hand of the Centurion, flew with greater speed, and arched directly toward the great multi-colored dragon. The beast altered its direction, but the missile changed its trajectory, flew into the thorax of the great beast. and exploded as a great bolt of Lightning.
“A Javelin of Lightning!” the Dark Sorceress marveled.
The jolt knocked the great beast backward and sheered several prismatic scales from its massive hulk. Several riders glanced backward and took heart at their comrade’s limited success. Three Centurions arched javelins toward the dragon and, just as did the first, the missiles flew into the beast. Bolts of electricity slammed into the creature, and with each impact the monster recoiled a bit. A hushed cheer came from the riders in the column. Then the dragon righted, roared, and belched a stream of white hot heat toward the seventy men scattered along the road. The flames consumed the thirty or so in the rear of the column and incapacitated many others. Surviving steeds panicked, threw their riders to the ground, and bolted away. The Captain tried to rally the survivors, but any capable of doing so screamed and guided their horses away from the beast. After a moment the Captain started to follow, but a bolt of electricity emanated from the beast’s maw and struck him squarely, ending his life and that of the magnificent firehorse that he rode. The dragon circled and spewed a ray of ice onto several of the fleeing Centurions. The fringes of the breath weapon touched the house and sent Burun and Mirian sprawling onto the ground.
