His first attack was as grisly as it was devastating. Forming a solid mass of Air, he slammed it down onto the largest concentration of Goblinoids he could see, who were bottled up on the grand avenue leading from the east gate and into the city, held back by the Arakites and the Ungardt. It struck like a mountain, crushing the Trolls, Waern, Bruga, and Dargu that were pressing the defenders' lines. The mass of Air was perfectly shaped to kill every Goblinoid in the street, yet did not so much as shiver the hair of the Ungardt and Arakites holding the line, nor did it collapse a single building. Goblinoid bodies were suddenly squashed under that invisible mass, reduced to gory red stains and blots on the flattened ground, their weapons and armor pulverized by the blow. The very few that had survived that attack, who were literally tied up in the lines of his people, were quickly cut down by the defenders. To their credit, they only gawked a moment before a quick-minded lieutenant commanding the Arakites barked a series of orders that caused them to reform into a moving formation, then began advancing back towards the wall step by step. Tarrin looked up, and then sent a multitude of tiny darts of magical power away from him, streaming glowing smoke as they streaked away, and they sought out and brought down every Harpy within a longspan of his projection. They streaked up into the sky and unerringly found Harpies, attacking those closest first, but each remaining one losing its bead on a Harpy once it was dead, only to turn in its flight and go after another. Tarrin recharged and released the spell again and again, sending out more than enough of the magical missles to find and kill virtually all the Harpies in the sky. Once that was done, he knew that the Aeradalla would stop fighting the Harpies and start shooting any enemy that moved on the ground below, adding to their confusion and terror.
Tarrin wasn't the only one to use powerful magic. Jenna had gotten up on the wall, and she was weaving a spell of her own, one so large and complicated that it took her nearly three minutes to finish it. When she was done, she raised her hands up towards the sky and released it, a sky which suddenly began to spin up clouds from nothingness. Jenna was manipulating the weather, the most powerful thing a Sorcerer could accomplish, and as the battle continued to rage, a dark, black, seething mass of clouds formed over the city. The sky grew darker and darker, incredibly dark, and rumbles of thunder began to run through the clouds above. When it was primed and ready, Jenna brought down her hands in a snapping motion, and an absolute avalanche of lightning, so much that it turned the sky bright, blinding white, lashed out from the clouds and came down into the human reserves still stationed across the fallow fields from the city wall. The lightning blasted through their ranks, exploding when it hit the ground, electrocuting the metal-clad men lined up in their neat rows-at least where the Elemental had yet to reach, anyway-and set fire to the grass in a heartbeat, leaving behind scorched earth and a large number of dead bodies. The blast of thunder that rocked across the city was loud enough to shatter windows all over the city, so loud that it was felt more than it was heard.
The wonderful thing about using the weather to attack was that the main energy needed to weave the spell was the part of creating the conditions. Jenna didn't have to fuel the storm to keep it going, only having to guide the quite natural processes that caused lightning, then direct it as it flashed from the clouds above. She had reached as far as she could reach with the lightning, enough to get a good part of the enemy reserves, but the rest were too far away for the lightning to reach, not without increasing the size of the storm. And Tarrin knew that she couldn't do that. She had made it as large as she could make it without inviting T'Kya's wrath. She kept raining lightning down wherever she saw a large concentration of enemies, moving the lightning closer and closer to the city to stem the flow of reinforcements. The Goblinoids that were trying to get into the city stopped rushing towards the walls, some of them diving to the ground, some of them turning around and fleeing back towards their army's reserves, some running in circles or in random directions.
Tarrin wove together a massive, intricate weave of Fire and Divine power, charging it with a great amount of magical power, then he released it. The Elemental spirit which answered his calls flowed into the magical construction he had created for it, and then it manifested before him as a gigantic scorpion of fire, fifteen spans long and with a tail ten spans on its own, dropping to the ground below. Tarrin instructed it to attack and kill any Goblinoids it could find, not to harm the humans, Wikuni, Were-kin, Centaurs, and Selani engaging the Goblinoids, and to render aid to their allies if it saw them in danger of being cut down by the Goblinoids. It assured him it understood the situation, and then waded into the fight with its fiery claws and stinging tail flashing out to strike at their enemies. Tarrin had dropped the Fire Elemental right in the breach, just behind the rubble of the wall, where it could assault the Goblinoids from behind even as the Arakites and Ungardt pushed them back into the Fire Elemental. Now he could concentrate somewhere else and allow his Fire Elemental to act on its own, adding more power to their efforts.
There was still stiff resistance, despite the power of the spells he and Jenna used. He absently incinerated a ki'zadun Wizard, who was using magic to send sheets of reddish fire up at the wall, fire from which the Wikuni musketeers recoiled savagely. Fire would ignite their gunpowder and kill them, and the Wizard seemed to understand that. When the fire stopped, the fifty or so odd Wikuni, all of them mismatched in appeareance but wearing those same red and blue uniforms, all knelt at the command of their officer and then fired their muskets down at a group of Goblinoids that had just climbed over the rubble of the wall. They pulled back to reload, and were replaced by a troop of Sulasian archers, who rained arrows down on the Goblinoids trying to crawl over the rubble of the wall until the musketeers were ready to fire again. The few that did manage to get over rubble alive were either blasted by Jenna's lightning, or found themselves facing a merciless Fire Elemental. They shrieked in panic and agony as Jenna's lightning pounded among them, and then the creatures, stunned by the thunderclap, were rent to pieces by the solid fire claws of the Elemental, or were speared by its tail, or were simply trampled under, where the intense heat the Elemental radiated set fire to their clothes, fur, and hair. Even a glancing blow from the Elemental left charred wounds in its wake, making the creature absolutely deadly to its enemies.
Tarrin saw that Goblinoids were still trying to climb up the walls. He saw a contingent of Arakites and Wikuni pushing ladders away from the walls with long poles, and in another area, they were fighting at close range with a large number of agile Dargu that had managed to get onto the wall. Tarrin realized that he'd wear himself out trying to kill them all, when he could simply do what Jenna did before him. Now that most of the enemy Wizards were dead, they wouldn't be able to stop them a second time. He drew in all the power he could, and then wove together the seven flows to form a Ward, charging it so it would last about an hour. Given the short duration, it allowed him to make its physical dimensions impressive, and he set it so that it ran about ten spans away from the outside edge of the wall, extending about a half a longspan from one side to the other. Wards had to be enclosed, continuous, so instead of a globe or sphere, he formed it as a rectangular box that was twenty spans wide, which brought the outside half of the wall into its area of protection. That made it as good as a wall, one that reached the whole area in which the Goblinoids were trying to climb the walls or enter through the opening Jenna had formed.
