Fusion was the advanced end of summon integration. Rather than just using the connection channel for resonance you pushed it further, allowing your summon’s abilities to layer over your own. The safest version was ability borrowing, pulling one specific capability from your summon and using it temporarily. The deeper versions involved much more complete overlap and were not recommended for first year students under any interpretation of the academy guidelines.
I was going to start with ability borrowing and work carefully from there.
"What ability would be least disruptive to start with," I said. Not quite a question.
Seraphine considered this with genuine thoughtfulness. "Enhanced perception," she said. "Vampiric senses are significantly more developed than human standard. Borrowing that layer would not affect your physical presentation visibly but would substantially improve your environmental awareness."
"Show me how to open the channel for it."
She walked me through the specific mental structure of a partial fusion pull. It was more precise than basic resonance. You had to narrow the channel to the specific ability layer you wanted rather than just opening the general connection. It took me four attempts to get the shape right.
On the fifth attempt it clicked.
The world went sharp.
Not visually exactly. More like the resolution of everything increased simultaneously. The conversations happening thirty meters away at the main training cluster became individually audible. The ground under my feet had texture I had not registered before. The air carried information, movement nearby, the specific heat signatures of the students around us, the distinct presence of every summon in the area.
I stood with it for a moment and let my brain adjust to the new input level.
"Manageable?" Seraphine asked.
"Give me a minute."
I filtered. That was the skill, not just receiving the increased input but learning to sort it, to push the irrelevant detail to background and keep the significant things foreground. It took about two minutes of active practice before it felt functional rather than overwhelming.
"That is useful," I said.
"It is a starting point," she said. "The deeper fusion layers carry considerably more than perception."
"We work up gradually."
"Of course," she said.
I was about to move on to the next exercise when the enhanced perception caught something specific.
Two sections over, half obscured by one of the wooden dividers, a group of three older students were watching the first year area with an attention that was different from casual interest. One of them had his summon active, a mid-tier shadow class creature that was currently doing nothing but was positioned facing our direction.
I kept my body language unchanged and filed the observation.
"Three students," I said quietly, not moving my gaze. "Two sections over. Older years. One has a shadow class active and pointed at us."
"I noticed them six minutes ago," Seraphine said, with the patient tone of a teacher waiting for a student to catch up.
"What have you assessed?"
"Curious rather than hostile," she said. "The shadow class is passive. Observation type positioning, not threat preparation." A brief pause. "One of them has been watching specifically the girl with the griffin, not you. Two of them are watching you."
I processed that.
The girl with the griffin was Evelyne, who was working in a section near the center of the grounds with composed efficiency, putting her griffin through movement drills with the focus of someone who had been planning this work for months before she arrived.
"Keep monitoring," I said. "Nothing changes unless their positioning does."
"Understood."
I went back to the fusion exercises and kept the borrowed perception active, letting the increased awareness run as background while I worked.
Twenty minutes into the session Maris appeared at the edge of my practice section.
He was alone this time. No satellites. That was different enough from this morning to be notable.
"Fusion work already?" he said, looking between me and Seraphine.
"Ability borrowing layer," I said. "Basic."
He was quiet for a moment. "I wanted to say something," he said, and his voice had shifted from the rehearsed friendliness of this morning to something more unguarded. "Earlier today I was doing the thing I do when I meet someone I perceive as competition. You probably noticed."
I looked at him.
"I noticed," I said.
"It was not my best quality," he said. He looked slightly uncomfortable with the admission, the way people do when they are being honest about something they would rather present better. "My father says I assess competition before I assess people. He is probably right."
I studied him for a moment.
This had not happened in the original story. The original Caelum had pushed back on Maris’s morning approach with enough cold condescension that the conversation had ended in hostility. This version of the interaction had no original text to reference. I was in a deviation already.
"Your father sounds like he pays attention," I said.
Maris let out a breath. "Occasionally to my detriment."
Something in me recalibrated slightly. The original story had written Maris as a straightforward antagonist. But antagonists in stories are written by authors who need them to serve a plot function. The actual person standing in front of me was a sixteen year old who had just come to a stranger and said something honest that cost him something.
"Work on the control exercises today," I said. "If your integration is as solid as you said it is then your precision should be ahead of most of the cohort. That matters more in the second month assessments than raw output."
He looked at me with an expression that was working through several things at once.
"Right," he said finally. "Thanks."
He walked off.
Seraphine waited until he was out of range. "You are collecting people," she observed.
"I am making fewer enemies than the original plan required," I said.
"There is a difference between fewer enemies and allies," she said. "Which are you building?"
I thought about that honestly.
"I do not know yet," I said. "But I know which direction I want to go."
She made that soft sound again, the not-quite-hum of someone filing something under a category they already had.
The sun was dropping toward the western wall of the academy grounds when the enhanced perception caught something it had not been listening for.
A sound from the far edge of the training grounds, near the maintenance path that ran along the outer wall. Voices pitched low and
