The Zemy Plains Incursion is the emergency assault that erupts after Raine and Leese, accompanied by Dyen, flee across the portal network while being hunted by Platinum-ranked assassins. Its decisive significance lies in the reversal at its center: the sisters appear to be prey moving from world to world, but their flight is ultimately a controlled retreat toward Cato’s support. Once they reach the Zemy Plains Conflict Zone, the pursuit becomes a public defense action, and Cato’s technological forces turn an apparently overwhelming assassination attempt into a demonstration of coordinated resistance against the System’s violence.

Causes and Background

The incursion grows out of the campaign against the remaining Sydeans. Raine and Leese are among the few Sydeans still visible, making them unusually valuable targets, while their builds leave no room for stealth Skills. Their pursuers are Platinums who can travel between worlds with little difficulty and can pay for rapid-fire teleportation across the portal network. The danger is therefore not simply that the sisters have been located; it is that multiple kill squads can converge on them faster than ordinary fugitives can disappear.

The chase crosses four worlds before the attack begins. That distance matters because the sisters are not running randomly. Dyen understands that survival depends on reaching worlds where Cato has a presence, and he stays behind them to ensure that they get far enough ahead. The movement through portals becomes a tactical calculation: every transition offers escape, but also gives the assassins another place to stake out, trap, or intercept them.

The Portal-Network Ambush

Raine and Leese detect the first attack a moment before a cloud of dark blades erupts from the walls near the next portal. Their movement Skills carry them away from the impact zone, while Dyen catches only a glimpse of the Platinum assassin before the attacker fades back into stealth. The assassin is a grayscale, furred frog-like species unfamiliar to Dyen, and the force of the attack is enough to shred Nexus walls made from Platinum-rank stone. The portal infrastructure is not a secure refuge; even the supposedly durable architecture of the System can be torn open by the hunters pursuing them.

The ambush immediately widens. Follow-up attacks come from another group that has either moved ahead of the fugitives or happened to choose the correct portal as a stakeout. Ice blades cut through orange poison surrounding the sisters, but Raine and Leese remain faster than their Gold rank would ordinarily permit. They reach a teleportation pylon and vanish before the combined attack can pin them down.

Dyen does not follow them at once. His priority is not keeping pace with the assassins but advancing the sisters one or two worlds farther toward Cato’s territory. He searches the portal area with perception Skills, identifies two traps, and triggers them with his rapier while jumping backward through a Nexus doorway. The maneuver delays him, and the assassination squads emerge from the teleportation pylon in close succession, yet the attackers do not realize that Dyen is worth tracking as a Sydean. His caution allows him to leave the town walls and continue after the sisters, even as the Platinum pursuers begin to close the distance.

From Pursuit to Defense Quest

The turning point arrives when Raine reaches the fleeing parties and gives the hunters a final choice: “Leave, or die,” she says, adding that the command comes from Cato. A crack of thunder answers from the cloudless sky, converting a warning into the unmistakable announcement of Cato’s arrival. At that moment, the pursuit is recast as an incursion against a defended zone rather than a private assassination attempt. The System formalizes the confrontation as the Global Defense Quest, “Destroy the Incursion,” assigning it a recommended Bismuth rank and placing it in the Zemy Plains Conflict Zone.

The quest framing exposes the System’s characteristic transformation of political violence into game mechanics. The assassins are not merely murderers pursuing refugees; they become an incursion, while resistance is converted into a ranked defense objective with a reward of an Overloaded C-Tier Skill. The formal label does not make the danger abstract. It gives the crisis a public, system-readable shape and signals that Cato’s intervention has become large enough to challenge the System on its own preferred terms.

Cato’s Counterattack

Cato joins the battle in full framejack, operating only slightly slower than the Platinums. His warframe weighs forty tons and combines industrial-strength muscle with monomolecular claws. He uses that mass and precision to punch through a gap in a crab-like assassin’s armor and gouge into the area where his modeling programs predict the vital organs should be. Aether radiation floods the warframe with unpredictable damage, but Cato accepts the loss because the machine is disposable and the Talis sisters have avoided the Skill. The battle establishes his method clearly: expendable biotechnology absorbs risks that would be unacceptable for living allies.

The defenders are technically outnumbered only in a qualified sense. Six warframes join Raine, Leese, and Dyen, although the three living fighters are not connected to Cato’s combat network. They compensate with independent combat ability. A Tornok Clan archer fires a seeking arrow that crosses the battlefield as a lightning-charged bolide, and Dyen emerges from the shadows behind the target to prevent further ranged attacks. When another crab-like assassin attempts to take flight, the Talis sisters intercept it, possessing greater aerial control than the warframes.

The fighting is short and brutally coordinated. The Zek sisters work together to tear apart another Tornok Clan assassin, and eight attackers include a large ratlike contingent, meaning that half of the opposing force belongs to that species. Cato’s remaining warframes grapple with enemy casters to prevent wide-range Skills, while combat algorithms guide the machines around System-empowered blows that would otherwise destroy them. Cato recognizes that he is less effective than Raine and Leese at exploiting openings, so he changes roles: instead of trying to finish opponents himself, he uses the warframes’ back-tendrils to hammer hands and feet, breaking stances and disrupting aim for the other fighters.

One warframe suffers catastrophic failure after absorbing the aether retaliation. Cato still has seconds to use it, and he throws the failing machine into the path of a massive shadow-ball in a deliberate sacrificial gambit. At the same instant, Raine and Leese descend from above onto the caster like falling weapons, having already eliminated the airborne Platinum. The entire battle ends in less than ten seconds. The assassins have no idea what has struck them, and the speed of the victory is itself part of the message: Cato’s forces do not merely survive a superior System assault; they can erase it before the attackers understand the shape of the opposition.

Consequences and Significance

The Sydean trio emerges with only scuffs and scrapes, while several warframes suffer grievous damage. Cato’s biotech cannot withstand higher-rank System attacks as well as Dyen and the Talis sisters can, but its disposable design makes that weakness strategically acceptable. The incursion therefore clarifies the division of labor within Cato’s resistance: Raine and Leese provide speed and aerial dominance, Dyen supplies stealth and tactical judgment, and Cato’s remote warframes create sacrificial openings and absorb punishment.

The event also demonstrates that Cato’s conflict with the System is no longer confined to hidden sabotage or isolated escape. The System’s hunters can pursue targets across worlds, but Cato can answer with his own network, war machines, and formalized defense. The Zemy Plains Conflict Zone becomes the place where flight turns into counterattack, where a kill squad becomes a recognized incursion, and where the apparent imbalance between System power and postbiological resistance is overturned through preparation, coordination, and expendable technology.
