Erwyn
Lord Erwyn Arryn marched at the head of his vanguard, his armor chased with rich blue enamel. The rest of the steel shone silver in the bright light of the sun as he and his forces made their way along the Goldroad to meet their enemies in battle. The Knights of the Vale marched directly behind him, their own armor polished and shining brightly as well. They were a resplendent sight, with the magnificent blue banners of their House fluttering in the wind alongside black and red Targaryen banners. With those banners flew hundreds of Pokemon, Staraptors and Tailows and Wingulls.
They had been marching for several days now, stopping and making camp when night fell and marching relentlessly during the day. Their objective was to ensure that the Starks and Lannisters did not reach King's Landing, or at least to slow them down a bit. And so they had set out to complete this task, knights and Pokemon alike.
They had developed a final version of their battle plan the previous night, estimating that this would be the day they would meet their foes in battle. It was a fairly simple idea. First the vanguard would charge and do their best to attempt to disrupt the enemy's front lines. Then they would pull back, appearing to be making a retreat. However, once the opposing forces followed them, the remaining knights who had not been in the vanguard would swoop in and take them from both flanks at once, crushing both their foes beneath their weight.
Suddenly, he heard a horn blow from behind him. Up ahead, he saw why the warning had sounded. Their targets were directly ahead, clad in dark iron and shining steel. He saw the grey Mightyena of House Stark flying alongside the golden Solgaleo of the Lannisters, as well as many other banners bearing the devices of the bannermen of the two Houses. There were Pokemon as well, and many of them. It was a fearsome horde, but the Warden of the East was unperturbed. Calmly, he turned to his squire and said, "Sound the charge."
The whole army knew what this blast of the horn was to herald. As it blew out loud and strong, a cry came up from the Knights of the Vale. They all began to run towards the opposing army, including their liege lord, who was still in the front, drawing their swords as well with an omnipresent hiss of steel on leather. Their Pokemon began to fly faster in turn, quickly overtaking their counterparts on the ground. Soon they were diving down towards their targets, wings and talons and special attacks raining down upon the grey and gold legion. Not too long after they were backed up by the knights, and the battle was joined.
The first foe Lord Erwyn met in battle was a Lannister soldier, accompanied by a Persian. The Pokemon was occupied fighting somebody's Pidgey, but the warrior in the Solgaleo-crested helm dared to raise his sword against him, hoping that there might be some title to be won in defeating him. The Lord of the Vale did not plan on going down so easily, however.
The two circled each other, each trying to find a hole in the other's defenses. Lord Erwyn was the first to find one; he struck hard and fast, thrusting his sword out towards the Lannister. The soldier turned the thrust aside with his shield, but even as he did the Warden of the East called down one of the Pokemon above with a gesture. All the trained Pokemon in the Vale were taught to respond to his call should he need them. That one gesture was all it took to send a Staravia screaming down from the heavens, pecking at the soldier's eyes and throat.
He turned around and disengaged the Lannister, turning his attention instead to a Bolton warrior off to his left. The Bolton was unaccompanied, and wearing only leather armor and holding a short sword. Erwyn fell upon the unwary soldier fiercely and mercilessly, swiftly carving through leather and flesh.
Suddenly, he heard a loud impact behind him. He turned to see his Swellow, Talon, had bowled over a Stark soldier who had been about to attack him. Lord Erwyn nodded approvingly, then went back to laying waste to his foes. Soon he had decided that it was just about time to put his plan into motion. However, just before he was about to signal the retreat, he heard a horn blowing to the east. It was not one of his own.
With terror in his eyes, he turned to see an entire second army coming in from their hind flank. The new horde was bearing the same banners he had previously seen coming from the front. There was no way to make the plan work now. They were completely surrounded. Even as he looked on, he suddenly felt a hot stabbing sensation in his arm. He turned and saw, to his horror, that there was a Houndoom there, it's fiery jaws clamped tightly around his forearm. He twisted to stab at it, but even as he did it's companion, another Stark soldier, came up behind him and slit his throat.
A few hours later, the majority of the Knights of the Vale had either been captured or killed in battle.
