I examine the description.

  I read it again. Then a third time.

  Three phrases land harder than the rest, ‘Reciprocal grievance’, ‘accelerated growth’ and ‘bond persists until one party is destroyed.’

  The System has given me the ability to create my own enemies. Enemies that scale with me. Enemies that learn from me. Enemies that cannot be avoided, cannot be outrun, cannot be resolved through anything except direct confrontation.

  High risk, high return. The hidden grudge mechanic, investments that yield results. Is that why the System pushed me so hard toward this class?

  I parse the words carefully. Sapience implies intelligence, so the Forsaken Stag had to be sentient enough to grieve. Necessity implies a driver, a catalyst, so in this case killing the doe to harvest the Core to protect Lily. Emotional Resonance could mean the act registered somewhere in whatever ledger the System keeps that's capable of tracking soul debts.

  Three conditions, all met. Only one of which was outside my control.

  Catalyzed... The System reminds me of Lily again, her presence, her condition. Why does her survival matter so much to it? She is just one of potentially thousands of sick kids across the city, tens of thousands across the metroplex.

  Beware. The System has issued warnings before, rare as they are. But never that word, never anything so direct.

  Something tightens between my shoulder blades. Pressure behind my eyes, spreading across my shoulders. I check Threat Hierarchy and my vision snaps to the north-facing window. The frame pulses crimson.

  I cross to the window.

  Across the highway as it carves into the underpass, at the very edge of sight, something stands motionless.

  Antlers first, wider than a doorway. Points catching the evening light in ways that seem wrong, bending the sun around them instead of reflecting it. Then the body beneath, simply massive. A full shoulder's height above any moose that ever lived, a frame built for war rather than flight.

  It is not hiding. It is not stalking. It stands there and watches the building I'm in.

  The way a predator watches prey it has already decided to kill.

  The Forsaken Stag. The mate. My Nemesis. The thing I made when I killed the doe.

  The notification echoes somewhere in my skull, unprompted.

  The Sanctuary is active but untested. I don't know its limits. Don't know if it can hold against something the System felt compelled to warn me about. Lily and Sofia both are still asleep, still recovering from whatever the activation cost was. The barricade held against the shimmer-creatures, but they were fodder.

  This is something else.

  If I stay, I'm betting that a creature intelligent enough to have found an anchor to its grief, to become something that warranted a warning, won’t throw itself against a barrier while I kite it until it dies.

  That is not how intelligence works. Intelligence finds angles. Exploits weaknesses. Wait for the moment you have to leave, have to move, have to expose yourself.

  Intelligence besieges.

  Unauthorized reproduction: this story has been taken without approval. Report sightings.

  And sieges are won by time. Time I don't have. Food I can't grow. Resources that exist outside these walls, in a city that belongs to something hunting me.

  I look at my Nemesis again. It hasn't moved. It knows where I am, knows I'm looking back.

  That's the point. This isn't a siege. It's an introduction.

  The bond hums at the edge of my awareness. I can feel its attention through it, its waiting, watching, considering.

  And I know first and foremost that impressions matter. Even between predators. Especially between predators.

  If I stay inside, I'm prey. Cowering behind barriers, waiting for the threat to lose interest, teaching it that fear keeps me still. Every interaction from this point forward gets colored by that first flinch. The System told me it would learn. The first lesson I teach it cannot be that I'm afraid of it.

  I killed its mate. I'm not going to pretend that didn't happen, and I'm not going to hide from what it cost. Whatever this bond is, whatever relationship the System has locked us into, it starts with me choosing how we meet.

  My Nemesis wants to see what kind of enemy it has.

  I intend to show it.

  I turn from the window.

  "Stay with her," I whisper to Sofia. "Don't open the door for anything except me."

  I pick up my spear and check the tape on the grip, wrapping it tight from a spare roll on the table. Down the stairs to meet my Nemesis. Fourth floor, third, second. Each step feels different than it did an hour ago. My lungs pull more air. My legs aren't burning the way they should after everything the Core took from me.

  I run scenarios while I descend.

  Direct engagement is suicide. My view from above told me that much. My Nemesis is moose-sized and built for violence. I didn't see plating or heavy fur when I checked, so I'm assuming my spear can hurt it. Its mate died on the same steel. But hurting something and killing it are different transactions entirely.

  I need external variables. Factors it can't control.

  Liberty Plaza sits two blocks south. I've passed it on supply runs into Summerhill and Peoplestown. Noted the burned vehicles choking the intersection to its east, the construction debris from when part of the overpass buckled a few hours in. Noted the feral hog packs too. Eight to twelve animals rooting through wreckage, System-touched and territorial. Charged me twice when I skirted their feeding grounds. I stayed my hand because I had big dreams for a smoker.

  I hit the landing and give myself a few breaths.

  If I can draw my Nemesis into Liberty Plaza, bring it to the eastern edge where the hogs claim territory, I can introduce competing interests. Maybe not enough to outright win, but enough to survive, maybe. To learn, to gather data on how it moves and what it prioritizes.

  I pull up the ability I've been holding in reserve. The list is familiar by now. I've been waiting for the right moment and this feels like it.

  Opportunist's Window pays out if the hogs engage. Fifteen percent damage against distracted targets. But that assumes my Nemesis lets itself get distracted. Something intelligent might not give me the opening even if I hand it to them.

  Contingency Protocol is a circuit breaker. Emergency stamina when health crashes. Insurance for when everything goes wrong at once. But picking a defensive option here feels like hedging when I should be building a position.

  Terrain Dividend is neither. Passive bonus near hazards and obstacles. Double bonus when the target is impeded. It doesn't wait for my Nemesis to make mistakes. It rewards me for fighting where the environment already favors me.

  Liberty Plaza is nothing but hazards and obstacles.

  I make my selection.

  I step into the lobby. Evening light cuts through the places where windows used to be, painting long shadows across the tile. I exit out of the building and head toward the underpass three hundred meters northeast. My Nemesis hasn't moved from where I spotted it. It stands in that shadow like it belongs there. Like the darkness arranged itself around the shape of it and decided to stay.

  I walk, not running, nor creeping, a measured pace instead. The spear rested across my shoulders, both hands draped over the shaft. Acting like someone relaxed, like someone who isn't afraid.

  Predator V Predator

  The posture is a lie of course, but lies have value when they're being priced correctly.

  Fifty meters out and even my convictions are starting to buckle.

  It's wrong.

  I knew it would be. The System notification mentioned transformation, catalyzed grief, an anchor finding purchase in something that used to be an animal. But knowing and seeing are different currencies.

  The antlers are the biggest I've seen. Sixteen points at least, maybe more, the tines branching in patterns that don't follow biology. Too sharp, too regular. Grown for violence rather than display, each point angled forward like a crown of pikes.

  The body beneath is moose-frame but stretched, wrapped in an arctic pelt, standing taller at the shoulder than anything that ran on four legs before the System. The legs are wrong too. Too long, joints articulated at angles that suggest speed I don't want to calculate.

  But the eyes are the worst.

  They track me with something I can't categorize. Not animal alertness. Not predator focus. Not even the intelligence of a human doing their best to survive. What stares back at me is the cold patience of something that has already priced me and likes what it found.

  The bond hums between us.

  That thread the System forced into existence behind my sternum, pulling toward the thing in the shadows. It knows where I am. Not through scent or sight. Through the connection itself. I could close my eyes and point to it.

  I suspect it could do the same.

  Twenty meters. I stop.

  My Nemesis doesn't move, doesn't react. Doesn't paw the ground or lower its antlers. It watches, waiting to see what kind of predator I am.

  Two predators meeting for the first time. Both of us pricing the other.

  I shift the spear off my shoulders and settle it into a fighting grip, but I don't close. Twenty meters of open ground between us, no obstacles, no terrain. Terrain Dividend sits dormant, waiting for conditions I haven't created yet. Out here I'm just a man with a spear facing something that outweighs me by eight or nine hundred pounds.

  I take a step backward, eyes locked on my Nemesis. Angling southeast, toward Liberty Plaza. Not a scramble, not a rout, a tactical withdrawal toward better ground.

  My Nemesis's head tracks the motion, those too-intelligent eyes narrowing.

  I keep moving. Backward steps become a slow walk, never turning my back, never breaking eye contact. The spear stays level between us, held off to the side. A statement of intent, nothing more.

  My Nemesis follows.
