A muster roll, fort by fort
Platoons with the Command they cost, and everyone in reserve beneath them. Level and experience, HP and MP, the five stats, movement, range and skill levels. One unit, or a whole fort at once.
Change your campaign without losing it.
Level a unit that fell behind, restock what you spent, hand a fort to another country.
What you change goes back into the slot. Everything you did not touch comes back exactly as the game wrote it.
Point it at your SaveGames folder and pick a slot. A dated copy is taken before a single field is written back.
Six screens, and the save behind all of them
The editor opens a slot, reads what is in it, and lets you write back only the fields you touched. Everything it does not model survives the round trip untouched.
Everything you own, and who carries it
Every weapon, piece of armour and accessory the save holds, spare or equipped, with the holder named. Search by name, filter by slot.
Treasury and season
The Mel you hold, the season the campaign has reached, and how long it runs for.
Who holds what
Every fort with the country that owns it, the level it has reached, and what the next one costs.
A copy before every write
Dated copies land in a folder beside your saves, one the game ignores.
The two stores a country keeps
Restock what you spent, empty what you will not use, or add a kind your campaign has never picked up, written from the game's own table.

What it looks like with a save open
The app borrows the game's own names and icons, so a screen reads the way the game reads. Six of them, one per thing the editor writes.
-
The treasury and the season.
-
Ownership and level, fort by fort.
-
The two stores a country keeps.
-
Every piece the save owns, and its holder.
-
Every copy, one click from going back.
A stat is not stored once
The number the game shows you is a sum. Write only the number and the next level up recomputes it from the parts, and your edit is gone.
stat =
base DT_Class
+What the class starts with. Named characters carry a base of their own.
fluctuationParam rolled once
+A per unit roll made when the unit is created. It is why two units of the same class and level do not share a stat line.
totalGrowthParam since level 1
Everything gained since level 1. Zero on a level 1 unit, rising with level.
Command set to 700 or 500, then one level up
-
totalGrowthParam
700 became 267
Reverted after one level up
-
fluctuationParam
500 became 506
Kept after one level up
So every stat edit carries the same delta into the roll as well as into the stat. Eight fields are mapped this way, and a stat lowered past its class base stops there, because the roll cannot go negative.
The game has no undo, so the editor keeps one
Before anything is written, a dated copy of your slot goes into a folder beside your saves. The game ignores it, and it travels with the folder if you move it.
- SaveGames/
- GameSaveData_0000.sav
- HeaderSaveData.sav

- GameSaveData_0000__20260901-143710-568.sav
-
Back up first
Whether pressing Save copies the slot beforehand. On by default, and the status bar says so while it is off.
-
Copies kept per slot
How many automatic copies survive. Older ones are pruned after each save, twenty by default.
-
Back up now
A labelled snapshot, taken when you ask for one. Snapshots are never pruned.
-
Restore
Puts a copy back over its slot. The version it replaces is backed up first, so picking the wrong entry stays recoverable.
Lowering the season is the edit to be careful with
Raising it is a number going up. Lowering it is not symmetrical. A campaign moved from season 19 back to season 8 stopped finishing anything already under way at end phase: units in transit, quests running, none of them completed.
The action queue appears to be stored against the season an action started on, so winding the clock back leaves those entries waiting on a season that has already been played. The editor does not model the queue, so it cannot tell a quiet campaign from one mid march. It shows the caution beside the field and takes the backup anyway.
Before you download it
Do I need the game?
Yes. It edits the saves the game makes, and there is nothing playable inside it.
Can I break my campaign with it?
It copies your save before every change, and you can put any copy back from inside the app. Back up your whole SaveGames folder before the first run anyway. It costs you nothing and it is your campaign.
Windows says it does not recognise the app.
It is not code signed, so SmartScreen warns the first time you run it. Choose More info, then Run anyway. Every build is produced by an automated pipeline from a tagged release rather than uploaded by hand.
I ran it and no window appeared.
It needs the Microsoft Edge WebView2 runtime, which Windows 11 and current Windows 10 already have. Install it from Microsoft and try again.
Can I edit while the game is open?
Quit to the title screen first, or close the game. While you are playing, the game keeps its own copy of the campaign in memory and will write over your changes the next time it saves.
Is there a Mac or Linux version?
Not yet. Only a Windows build is published today.
Open a slot and see what is in it
Nothing is written until you press Save, and the copy is taken before that.
Version 0.2.0. The first build is not published yet.
- Windows 10 or 11, 64 bit
- No installer. Unzip it and run it.
- Needs the Edge WebView2 runtime, already on most machines
- Free, and there is no account to make
