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.
