Far east of Warshawa, there is The Lost. Having been pushed by a combined force of adventurer vanguard, and standing army of the Kingdom of Palmera. On the back foot since the beginning of the invasion, mainly due to their equipment not being suited against magical targets. Rogue wizards from the past were always dealt with by outnumbering them, now they are the outnumbered. The presence of magic had long been believed to be the leading cause for mutations, and only the lucky ones turned into the civilized mutants that roam the settlements. However, this theory was quickly disproven when there hadn't been a single mutation ever since the Central Governor took over.
Robert the necromancer did plenty of tests regarding it, using some captured animals normally vulnerable to mutation. There were plenty of mages experimenting on this across the world, and Robert was one of them. He was hunted out of his tower, and away from his fields by the rampaging adventurers. The Lost had managed to rescue him, and many of his other colleagues, from the Agricultural Union. They hadn't seen eye to eye very often, especially considering Union lands were hotbeds for mutations in the past. That time has now ended, now that the main sources of food are being uprooted, their enemy makes up for this deficit by importing massive amounts of food. Like many of his more magic capable colleagues, Robert took the loss of his home in a manner many would describe as insane, he himself would describe it as an attempt to remain relatively sane.
"Hi guys, my name is Robert the necromancer, and today we are doing another unboxing." He jams his shovel in the lid of the casket, and breaks it open to reveal a fresh corpse of a soldier beneath.
"Looks like we have a high quality specimen here guys, look at that physique! What do you think chat? You think we got a potential candidate to act as a core for a flesh golem?" The ravings of the necromancer are the only thing keeping a man that now resurrects things to take life instead of cultivating it sane.
One of the nearby soldiers nearby nudges his fellow grunt, he twirls his finger at the side of his head, while pointing at the necromancer with his other finger. They share a short snicker as they watch the necromancer rummage through the corpses they brought. Giving the corpses to the necromancers who fled eastward has become standard procedure, not because of command saying so, but because they need every body whether it died once or didn't.
"Deadly anomalies, dangerous mutants, adventurers and invaders! None of them will stop The Lost on its triumphant march towards salvaging the planet! The world fears the Governor's expansion, join The Lost, and save the planet!" The speakers set up at the nearby town blasts propaganda from above, many have answered the rallying cry of The Lost.
Nearby the settlement, where The Lost have temporarily set up. Some odd individuals hide in the bushes. An [Oni], a [lizardman], an [Arachne], and a [Gnome] watch the people in their routine. The oni carries a massive studded metal club, the lizardman carries spears made from bone, the arachne is clad in full black metal armor, and the gnome is equipped with multiple clockwork contraptions. The Monstrously Strong Squad, as is their adventurer group name, are plotting how to take the weird cult out.

"They don't look that impressive, I bet I could crumple them with ease." The oni is confident in her strength, but doesn't charge in like an orc would have. She's smart enough to wait for the input of her teammates before charging in mindless regardless.
"Do not be fooled, that one cracking open crates is a necromancer. They always have tricks up their sleeve." The lizardman doesn't break his sight away from the necromancer, like a hunter watching his prey.
"I heard that this world had some odd morals, with how they apparently rarely use magic, but of all things tolerate... necromancers, but it's really something else to see it in person." The arachne is simply idling, tapping her halberd against the black armor covering her.
"Not just tolerate, downright friendly, if you ask me. The corpses that necromancer is working on are their own. Even cults back home aren't this extreme when it comes to providing materials for their dark arts. Regardless, get ready." The gnome inches closer, pointing an enchanted automatic crossbow in the directions of the standing soldiers.
As soon as the first soldier goes down, the necromancer lifts a corpse to block whatever comes his way, a wet noise hits the corpse, and a bone spear now sprouts from it. The remaining soldier hides behind a rock pillar, and gets out his walkie-talkie. The necromancer says some words, and moves his hand about. All the caskets begin to shudder, and break open from the inside. The undead coming from the caskets move to intercept a charging arachne, and manage to stop her advance. The oni however, barrels through the undead, but retreats when she gets hit by death magic attacks. So far all attacks have been getting reliable blocked by The Monstrously Strong Squad thanks to their superior magical protections. The gnome and lizardman keep Robert pinned, while the oni and arachne cut through the dwindling undead in an attempt to reach him.
Just as the last undead are crushed, the roaring of a mighty chariot is heard over the battlefield, and the odd noise of the flying metal beasts erupts over the area. Multiple armored vehicles enter the battlefield, and 2 helicopters begin circling the zone like vultures. The necromancer runs away from the battlefield, while the soldier that went forgotten reappears from behind the stone pillar.
"Reinforcements? I didn't detect any magic flares!?" The gnome is surprised, but shoots at one of the helicopters flying overhead. The pathetic little crossbow bolt was fire by an enchanted crossbow, and detonates as it hits the helicopter. It quickly goes down as it completely lacks any magical defenses.
The Lost charge in to cover the necromancers retreat, but their guns fail to pierce through the attackers. Men fall to dragon bone spears, the last helicopter gets downed after attempting to evade the fate of its comrade, tanks get crushed by a large steel club and attacks are blocked by the fully armored arachne. Citizenry attempt to flee from the fight, but many die in the crossfire from both sides. Many more yet take up arms to fight with The Lost, only to join in their fate. As the Monstrously Strong Squad cleans out the last area's of resistance, they begin sifting through their spoils. Heaps of processed metals disappear into their spatial pouches, to be sold to the highest bidder.
Throughout it all, the speaker installed by The Lost doesn't cease its automated broadcast.
"Free citizens, religious folk, necromancers. Join The Lost, protecting the world from [The Veil]'s evil is our common goal."
