Marvin stepped onto the first rune.
The corridor reacted immediately.
A faint vibration traveled through the floor, sharper than before. The runes along the walls dimmed, then brightened in a new pattern. The wisp flickered once, hovering slightly to the left.
Wrong.
Marvin stepped back.
The vibration stopped.
He didn't rush again. His eyes moved across the floor, studying the arrangement. The runes were not random. Each carried a slightly different glow—subtle variations in intensity, almost unnoticeable unless observed carefully.
He crouched.
The first rune he had chosen pulsed too fast. Not unstable—impatient. The inscription on the wall surfaced in his mind.
Those who follow the first step see what the second conceals.
First step.
Not fastest. Not brightest.
First.
Marvin shifted his focus. There—near the edge. A rune dimmer than the rest, nearly overlooked. Its pulse was steady, quiet, consistent.
He stepped on it.
Nothing happened.
Then the corridor exhaled.
The pulse beneath his feet aligned with the rune. The wisp drifted forward, brighter now, stopping above the next symbol.
Marvin followed.
Second step.
This rune looked identical to the others, but the moment he focused, he noticed the difference. Its glow didn't match the walls—it lagged slightly behind the rhythm.
Concealed.
He stepped on it.
A ripple moved outward. The walls responded, runes shifting position slightly, like gears aligning. The shadows pulled tighter into the corners.
Marvin didn't move.
He watched.
The sequence was revealing itself. Not through force, but through rhythm. Each correct step synchronized him further with the House.
The third rune appeared.
Not physically. The space between two carvings distorted faintly, forming a hidden pattern. Without the previous steps, it would have remained invisible.
Marvin stepped forward and placed his foot exactly between the two runes.
The corridor went still.
Then—
A low hum spread through the walls.
The entire sequence lit up.
Lines of light connected the floor runes, forming a complete pattern. The path ahead extended, the corridor straightening, no longer twisting. The obstruction was gone.
Marvin exhaled slowly.
"Not a trap," he said quietly. "A filter."
The wisp hovered at the end of the sequence, pulsing once before drifting further ahead.
Marvin stepped off the final rune.
Behind him, the sequence faded.
Ahead, the corridor widened.
And someone was standing there.
Not a shadow.
Not a wisp.
A person.
Tall. Still. Watching him with clear awareness.
Marvin stopped walking.
The figure tilted their head slightly, as if confirming something.
Then they spoke.
"You're slower than the last one."
Marvin didn't lower the crystal.
"Then I'll make fewer mistakes."
The figure studied him for a moment longer.
Then, without another word, they stepped aside—revealing a door behind them Marvin hadn't noticed before.
The runes around it were different.
Sharper.
Older.
Marvin's gaze shifted from the figure to the door.
He didn't move immediately.
Neither did the stranger.
