The archive
Library of Kagami
Professor Phineas Phantomhive II keeps watch over field notes, disputed maps, recovered testimony, and chapters that may describe moments which never happened. He insists the catalogue is reliable.

MirrorGate
Somewhere inside an Obsidian vault waits a world that was never meant to stay still. Its records speak of Zerkalo, where mirrors remember other lives, roads misplace entire centuries, and the wounds of an ancient divine war have begun to dream again.

01 Inside the vault
Every shelf
points elsewhere.
Nothing in the vault stands alone. A royal name opens onto an old war, a creature points toward a broken age, and every unfinished story leaves another door ajar. All paths begin in the Library of Kagami.
The world
Zerkalo
A realm built over wounds no kingdom can truly claim. Beneath palaces and borders lie the remains of the Primordial War, still waiting to reveal whether they hold salvation or the shape of the next catastrophe.
The threshold
The Mirrorgate
Not a road or conventional plane, but a distorted passage through reflection, memory, folded distance, and broken chronology. Some mirrors show a face. Others wait for an invitation.
Hansha & Lustro
Primordial War
Shattered Hope Era
Blackwood & Phantomhive
Shard Monsters
Pack in the Twilight
02 Planned journeys
Eighteen ways
to get lost.
Every planned adventure belongs to the same setting. A single night beside the wrong mirror may end at dawn, or return much later as the first thread of a history the players have already changed.
Planned / Standalone
10One-shots
Ten doors into cursed estates, forbidden archives, unstable scars, and mirrors that promise to open only once.
Planned / Short arcs
5Short adventures
Five deeper trails where local conflicts expose recurring faces, dangerous relics, and consequences that refuse to remain where they began.
Planned / Long term
3Campaign frameworks
Three long shadows cast across the Shattered Hope Era, where crowns, divine wounds, and the Mirrorgate can reshape an entire table’s version of Zerkalo.
Roadmap: These numbers describe the intended complete collection. MirrorGate is still in early development, so individual stories and their order may change as the setting grows.
03 Beyond adventures
The vault
keeps growing.
Some records are meant to be read. Others are meant to be carried into a campaign, worn by a character, awakened beneath a ruin, or encountered when the party realizes it is no longer alone.
World & history
The oldest records disagree about Zerkalo, the Primordial War, and what truly began the Shattered Hope Era.
People & powers
Royal bloodlines, veiled factions, watchful gods, divided cultures, and names that appear more often than coincidence allows.
Monsters
Shard-born things already haunt the records. More wait beyond the pages that have been safely catalogued.
Adventures & fiction
The Pack in the Twilight and the Shattered Hope campaign frame are among the first threads pulled from the dark.
Subclasses & feats
Character options marked by old blood, living reflections, divine echoes, and time that no longer moves in a straight line.
Magic items & more
Relics, tools, hazards, and other objects whose histories may be more dangerous than their powers.
04 Open the archive
Enter through
Obsidian.
MirrorGate does not expect to be read from beginning to end. It expects curiosity. Open the repository as an Obsidian vault, find the welcome record, and follow whichever name first feels familiar.
Open source / Explore freely
The door was never locked.
Take what your table needs, change what the records got wrong, and follow the wiki-links until the vault begins answering questions you never asked.

The Library of Kagami awaits
The realm is
unfinished.
That may be the first thing inside it that tells the truth. Read the records, borrow what your table needs, and leave behind a version of the Mirrored Realms that did not exist before you entered.
