OVERVIEW
This companion runs alongside your physical game. It handles the mechanical side: draws, rolls, stat tracking. Your notebook is still where the story can live. The app just offers the option of an all in one play experience. Use some of it or none of it, the choice is yours!
Your session saves automatically to your browser. As long as you use the same browser and don't clear your cache, it will be here when you return. The SAVE tab lets you export a backup file to your device — recommended if you clear cookies regularly or want to move between browsers.
TRACKER TAB
LOYALTYTap + or - to adjust by 1. Tracks commitment to the mission and CHARON. Can go negative.
UNCERTAINTYSame controls. Tracks erosion of certainty and growing doubt. Prompts marked +/-(L) or +/-(U) tell you which stat to adjust. Your roleplay determines the direction and how much.
CYCLE COUNTERPress NEXT each time you complete a cycle. RESET returns to 1. The chapter selector shows the suggested cycle count for that chapter.
NOTESTake notes here as you play, they will also appear in your log tab to reference when making your formal logs!
ROLL D6Rolls a six-sided die. Result is flagged EVEN (success) or ODD (failure) to match how some cycles read dice outcomes. Last 8 rolls are kept in history.
CARD DRAWDraws from a shuffled standard deck without replacement. Suit counters show remaining cards per suit. Use the suit buttons to draw from a specific suit, or ALL for the full deck.
RESET DECKReshuffles all 52 cards back in. Use when starting a new chapter or when the game instructs a reset.
DISCOVERIESTap a numbered square to mark a discovery found. Tap again to unmark. Numbers match the Discovery items in the game text. Use the link to access the discoveries online as well!
LOG TAB
NEW ENTRYOpens the entry form. Current cycle, chapter, and stat values are stamped at the top automatically. The body is freeform: write in character, out of character, or a mix.
COMMIT ENTRYSaves the entry. It appears below, newest first, with its stamp intact. Individual entries can be deleted with the X button.
CLEAR LOGDeletes all entries. Asks for confirmation. Cannot be undone, so export your session first if you want to preserve a record.
DOSSIER TAB
Character sheet for your crew member. No fields are required. Leave things blank if your character's memory level does not allow for them. Or fill it all in and select your memory level for a randomized experience. To recover memories, use the MEMORY RECALL button and select what stage of recovery you are in! The extended notes panel on the right is useful for tracking CHARON's statements, inconsistencies you have noticed, and anything your character is keeping private.
SAVE TAB
Your session saves automatically to your browser whenever you make a change. Use the SAVE NOW button for manual confirmation. The backup file options let you download a copy to your device or transfer your session to another browser — worth doing if you clear your cache regularly.
EXPORT SESSION FILEDownloads your session as a file called antumbra-[name].json. Think of this as your save file. Keep it somewhere you can find it — your desktop or a documents folder works well.
IMPORT SESSION FILELoads a previously exported file back into the app. Use this to resume a session. It will replace whatever is currently showing, so export first if you want to keep it.
EXPORT LOG AS TEXTDownloads your log entries as a plain .txt file. Use this if you want to read your session notes outside the app, print them, or keep a separate written record of your run.
RESET ALL DATAWipes everything: stats, log, discoveries, dossier. Use when starting fresh with a new character. Export first if you want to keep any record of the previous run.
NOTES
The suit selector works like a dial: click a suit to draw only from that suit, or ALL to draw from the full deck. Only one option is active at a time.
Stat values can go negative. The display handles the minus sign automatically.
