"2nd Artillery Division, FIRE!"
From 1 kilometer to the West shines a bright light, brighter than any Golem Core a thousandfold, and the Ruins are suddenly struck by the purifying power of arcane sunlight. The beam is massive in diameter, painting the entire structure's West wall a glowing white. Despite no damage befalling the Ruins' stone structures, Dervishes caught in the blast are utterly disintegrated and returned to their component pieces, while spellcasters from all factions find themselves incapable of casting. Those who can take cover in whatever shadows they can find, scrambling for shade as the holy light saps their power.
The beam peters out, and while the Abyssian and Vetruvian forces wonder what new enemy has appeared, Argeon barks his next commands to a Lyonar communications mage.
"1st, 3rd, and 5th Infantry Divisions, FORWARD! Advance Squadron, FORWARD!"
A line of shadows appears over the horizon and then begins the advance downhill, as if the world is pouring liquid war into the valley of the Ruins. Droves of Silverguards and Dragoons march down the mountain, no doubt conserving their strength for later. Running ahead of them are the tireless Windblades, light infantry trained to chase down stragglers. Insurmountable force and inescapable speed; the Lyonar never deal in less than extremes.
To the surprise of the gilded invaders, many sizable threats have survived the initial bombardment, and more forces are emerging from the shadows of the Ruins.
"Halt advance! Ready shields!"
The well trained Lyonar army stops and shields itself in one breath, immediately deploying their Aegis Barriers and taking shelter behind them. It takes but a moment and, as Abyssian spellcasters emerge to strike back, the second artillery strike begins.
Again, white light scrubs the battlefield of power once more. Sunlight bends and contorts itself around the Aegis Barrier, leaving the Lyonar armies untouched. The advance begins again, and the crippled forces of the enemy are fleeing to the relative safety of the Ruins.
The Horrors, however, are standing their ground, unaffected by the light thanks to their lack of eyes. A mere 50 meters away now, the Lyonar army breaks into a sprint and meets them head on. It takes barely 2 Windblades to finish a Horror, but the casualties may reach more than the Highmayne would allow.
"Infantry Divisions, BACK! Airdrop Division, FORWARD!"
An Aerial Rift opens above the Ruins, and 10 ornate, golden balls fall from the sky. The Lyonar ground forces retreat temporarily and watch as the balls bowl over multiple Horrors with the force of their impact. The golden balls unfold and reveal themselves to be Ironcliffe Guardians, entering hand to hand combat with the Horrors and eliminating them.
Zir rode up beside Argeon on his steed and saluted him. "General, reporting in! The exterior of the Ruins are free of Abyssian menace!"
"What about the sandybots?" growled Argeon.
"The Vetruvian are also neutralized, dead or fled! All of our enemies seem to be within the Ruins!"
"Good, good." Argeon wiped purple blood from his blade, surveying his forces. "We will take the Ruins before sundown. Call the heliomancers in from the artillery outpost and prepare them for extermination. I want this whole area scrubbed and Sun Bloomed. The scum won't have a chance in hell of laying their roots here."
"Of course, General."
Argeon barked a hearty laugh, straight from the gut and devoid of kindness, the laugh he only derived from the cruel amusement of conquest. To imagine, so many key Abyssian Generals in one spot with limited forces. He licked his lips wickedly.
"We cannot lose!" he shouted. "It is as they say: Deus Vult!"
