Horatio Isodore
Location: Classified, Great Britain
Horatio knew that a great threat loomed over his forces, and, by extension, all of Arcadia. Some great power had made itself known, and nearly every devil on the planet could feel it. This caused great concern for Horatio, for he knew that an entity with this magnitude of strength would not be content simply with existing on a planet, but had far more sinister intentions, and no one was safe. Nevertheless, Horatio was undeterred, concerned, but not afraid, for he knew that no threat existed that did not have a way to be defeated given enough time and proper preparation. When and where this threat would make itself visible, he could not predict. It was time to prepare for a worst case scenario, that he would have little time to react to this phantom threat, and needed to make every second of action he did have count.
The first priority would be to reinforce every single centimeter of this underground bunker, to make it as unassailable as possible, should the enemy already know of its location and be either preparing to or on their way to strike. Housed within the bunker was the colony's most important asset, the terminal, a portal that opened a gate to hell itself. He knew this was to be defended at all costs. Should the enemy get their hands on this important interdimensional junction, not only would it prevent any infernal forces to march into Arcadia, grinding its conquest to a screeching halt, but one would be able to land at the very shores of Infernum itself. Horatio knew he could not let an asset of such import fall into anyone's hands, least it be used against Infernum. He and his commanders would take every single form of defense into consideration when addressing reinforcing the integrity of the bunker, and to do so immediately. Assuming the enemy did not possess knowledge of its location, the devils would also go about making it as undetectable as possible, from magical sensors or otherwise. This would involve complete radio silence effective immediately.
The next thing to do would be to identify the enemy. This would involve establishing telepathic communications with all scouts on the ground, in the air, under the sea, and everywhere in-between on the planet. Have them always travel in groups and search all the four corners of the globe to identify this alien threat. They would make sure to of course, steer clear of any territory already held by the other factions.
The next step would be to prepare his forces, the bulk of which stood just behind the portal, awaiting their master's orders. It would not be used much as a show of force though, doubting that an enemy of such caliber to be intimidated by an army it would see as inferior, but he could use the enemy's hubris to his advantage. Horatio would have none but the toughest and most trained warriors in his vast legions guarding the bunker at all times, but would have the rest of his billions of infantry, cavalry, artillery, vehicles, mechs, and various other instruments of war deployed all across Britain. Naturally, he would establish fortifications upon the highest hills, but he would also invest sending vast amounts of his troops to areas that had little to no strategic value in keeping, making the enemy think that one such location was important when they were not, while attracting little attention to places that were, such as the bunker. He would further bolster the appearance of security by utilizing illusion magic, so as to seem to possess greater numbers than were actually present.
Simultaneously, he would send some of his servants to negotiate with the other factions not to attack his forces, telling them that Horatio's army were preparing to counter a different threat, and to convince them that this threat loomed over everyone's head as well. Horatio would then negotiate open radio communications with Infernum's colony, sharing information that could be vital to detecting and addressing any threat. Horatio knew that information was the key to winning any conflict, and with open access to it, he could act and react to any and all of his opponent's moves. Now thy enemy, his movements, and strike at critical times and junctures. That is how you win the game.
A metaphorical chess match between this mysterious force and Horatio had just begun, and Horatio would make sure to seize the initiative and make the first move. From now on, he would ensure that the enemy would dance to his tune, and make this enemy fall the way countless others have fallen before him.
