Horns bellowed in answer to the screaming trumpets that sounded from the high towers of the concentric castle. The starless night was suddenly bright with globes of glowing light, radiance that shed betraying illumination behind the lines of besiegers outside the fortress. Men and machines were moving across the trampled ground toward the great stone walls. Arrows, quarrels, and streaking missiles of magical origin flew toward the encircling soldiers. Some arrows and quarrels lodged in wooden mantlets or struck into shields, but others sank into flesh. The magic missiles, blazing fireballs, and crackling bolts of lightning were far worse. Bodies were tossed high by roaring blasts; wheeled shelters were split and broken by the flashing strokes of electricity while metal-clad men-at-arms behind them became charred corpses. Varicolored darts sped unerringly into hapless targets who screamed and died. Torrents of flame erupted from the sky to set siege towers blazing, giant torches that added a hellish light to the scene, while raging fires swept over the advancing lines or made curtains of flame that seared their flesh.

From these conflagrations sprang huge, manlike forms. The very flames formed them, and these great things strode forth from the fires to further wreak death and destruction on the attacking army. Glowing tentacles sprouted up from the earth itself and wrapped their fiery coils around war machines and men. Flesh and blood could not stand such an inferno. The lines of soldiers quickly became scattered, fleeing men seeking escape from flaming death, their ranks decimated, all cohesion gone. Arrows and buzzing crossbow bolts sought out the retreating attackers and exacted further toll, while chains of blazing, blue lightning leaped among them, slaying and completing the devastation.

The battle was not all one-sided, of course. While the defenders in the great castle wrought their destruction, the ringing soldiery had countered with showers of arrows, but parapet and merlon protected the defenders, and bolt and shaft most often splintered harmlessly against stone. Rocks and boulders smashed into bartizan and tower, impacted wall, or arced over into the courtyard, before fire silenced catapult and trebuchet. Thick, spearlike missiles flew also, until, likewise burned, the ballistae that shot them forth were blazing bonfires. There were a few, pitiful spells cast too – silvery darts and opalescent rays of cold light, even a few blasts of fire – but these had slight effect. It seemed that the spell-casters of the besieging force were unable to withstand those within the great fortress, for the former had to work relatively unprotected, while those within were not so exposed. Abruptly, the scene changed.

Almost simultaneously, the bright spheres of light that revealed the attacking army went out. In turn, the sky above the castle was bright, and the place was illuminated with something that resembled the light from a full moon, while the area round about its walls was dark, save for burning equipment and fiery elementals still delivering death. As all this occurred, drenching bursts of rain issued forth from directly above the huge fire elementals, while gentler precipitation fell upon burning wood. The fire elementals, four in number, hissed and roared their anger and pain as the pelting drops of water vaporized upon them, sending forth steaming clouds and cooling the monsters' flames.

One of these glowing elementals was near the partially filled moat. A pillar of water suddenly arose, formed itself, and grappled with its fiery counterpart. Even as the two giant elementals struggled, a new sort of elemental creature arose from the rain-soaked earth, this one formed of damp dirt and stone and clay. Earth and fire contested, as did fire and water. Men watching from the castle or the surrounding camp of the besiegers saw the blazing fire elementals' flames become smothered and wink out.

Bass twangs and thumps came from the encircling force, and arcing boulders and massive spears again rained upon the curtain walls, the towers, and the castle courtyard and buildings inside it. The radiance illuminating the fortress was extinguished but almost immediately replaced by globes of light such as those that lit the scenes behind the attacking forces. Some hung above the place; others seemed to emanate from turret top, bartizan, and tower. The contesting spell-casters seemed to be playing a game, for globes of utter darkness would intermingle with the bright spheres and neutralize each other, while yet fresh lights would spring up elsewhere.

As this all occurred, the defenders on wall and tower were plain to see, and sniping fire from longbow and heavy crossbow began to score successes. Here and there, men dropped after suddenly sprouting a clothyard shaft or the feathers of a thumb-thick crossbow bolt.

The rumbling and murmur of advancing troops were again discernible to the castle's defenders. Despite the terrible punishment dealt to their initial foray, the troops were again advancing to storm the walls. Somehow, the soldiers had been rallied, reinforced, and sent back. Trumpet and drum sounded within the fortress, calling every possible defender to man the walls for a last defensive effort. Their magic-users and clerics had spent their powers on the destruction of the first attack; the fresh assault would have to rely on flesh and blood, armor and weapon, to hurl the attackers back from the stronghold. The castle's own, smaller versions of the attackers' war machines were put into play. Springnal and catapult began working while rocks were readied, cauldrons of burning charcoal and bubbling oil swung out over machicolated battlements, and ram-catchers assembled.

A column assembled in the outer bailey. The great gates of the fortress were opened, the iron portcullis winched up, and the oaken drawbridge let drop with a clatter and a bang. Out into the pale morning came a swarm of hulking, mailed ogres brandishing huge morning stars, six-foot swords, and other massive weapons.

With them were even more malign creatures – a score or more of hideous trolls, monsters needing no weapons save their iron-hard talons and teeth. Their stooped, shambling gait made the trolls seem smaller than the thicker ogres, but occasionally one would stiffen and stand upright to peer ahead. Then their height, more than half again man-size, and a full head taller than their ugly companions, could be seen. Huge trolls and great ogres, nearly a hundred in total, issued forth, crossed the oak of the drawbridge, and fanned out. These were the terrible advance guard of the castle's sally.

More trumpets blared, and behind the advance guard came a force of gnolls – hyena-faced things, seven feet tall, and armed and armored as men would be. Their great bows taut, bardiches and glaives ready, they came in hundreds, barking and giggling as they advanced, lusting for the feast of battle and flesh to come. If the castle was besieged, it by no means felt itself at the mercy of the army doing so.

"At last. The filth from below is vomited forth!" Thus spoke the general commanding the ringing host. As he said this, he waved his arm in a signal, and the echoing rumble of kettle drums filled the morning.

Bristling phalanxes of pikemen, supported by mailed cavalry, moved to meet the ogres and gnolls, while archers and crossbowmen began to direct a flaming volley of burning missiles toward the knots of rampaging trolls. The field before the castle gate was quickly swirled with men and humanoids locked in mortal combat. Champions and spell-casters of the attacking army were now engaging the trolls, immune as they were to most harm that ordinary folk could cause. These contests were terrible things indeed, and many men fell before the on-rushing green monsters. This pleased the crimson-robed priests who observed the melee from the castle's highest tower. The bright light of the sun climbing higher into the heavens, however, also revealed a curious fact to these observers. Where ranks of charred corpses and slain bodies should have been, the commanders of the fortress saw only slight evidence of the slaughter which had been wrought by spells and elementals before daylight. Instead of soldiers slain in windrows and devastated by firestorms, there were but scores of dead, not hundreds or thousands.
