Three documented 4×4 candle arrangements use empty, unlit, and lit states. Their purpose remains unknown.
UnsolvedSetup: Three candle arrangements have been documented on 4×4 stands in the underground tombs. Across the complete stands, candles occupy six coordinates: A1, C1, C2, B3, A4, and D4. One arrangement retains only unlit candles at C1 and D4, another has all six candles with three lit, and the third has all six lit.
The 4×4 format recurs: The same grid dimensions appear in the boiler room panels (×15), the boiler room elevator top, the attic box, the garage gas tank, the darkroom lower cabinet, the conservatory box, the pool dig spot, the tunnel to the sanctum doors, underpass hallway walls, throne room pillar bases, and more. Shared dimensions are confirmed; shared data or encoding rules are not.
Three observable states: Each cell can be recorded as empty, occupied by an unlit candle, or occupied by a lit candle. This supports a ternary transcription, but it does not establish that the game treats the states as numeric values.
No confirmed input found: No 4×4 input mechanism has been identified. The 2×8 trophy import screen in Blackbridge Grotto is another 16-cell interface, but no connection to the candles has been demonstrated.
Alzara connection: The candles appear in one of Alzara's visions, but they cannot be interacted with during the vision sequence.
Transcribed from annotated in-game screenshots. Columns run A-D from left to right and rows run 1-4 from bottom to top when facing the stand. The matrices below are written from row 4 down to row 1. 0 means empty, 1 means an unlit candle, and 2 means a lit candle.
Grid 1 (2 candles, 0 lit) Row 4: [0,0,0,1] Row 3: [0,0,0,0] Row 2: [0,0,0,0] Row 1: [0,0,1,0] Grid 2 (6 candles, 3 lit) Row 4: [2,0,0,1] Row 3: [0,1,0,0] Row 2: [0,0,2,0] Row 1: [2,0,1,0] Grid 3 (6 candles, 6 lit) Row 4: [2,0,0,2] Row 3: [0,2,0,0] Row 2: [0,0,2,0] Row 1: [2,0,2,0]
Three arrangements have been documented. One contains two unlit candles, one contains six candles with three lit, and one contains the same six candle positions with all six lit. Every cell can therefore be transcribed as empty, unlit, or lit.
The same dimensions recur across the estate: boiler room panels (×15), boiler elevator, attic box, garage gas tank, darkroom cabinet, conservatory box, pool dig spot, tunnel to sanctum, underpass hallway, throne room pillars, freezer servers, classroom chairs, and more. Their contents and functions vary, so the shared format does not by itself establish one encoding system.
A knocked-over candle stand still preserves the same row and column spacing, with some candles absent. This confirms the physical grid layout, but not whether the candle states encode information.
The tomb candles are shown in one of the Great Alzara's vision sequences. However, they cannot be interacted with during the vision, and Alzara doesn't directly reference them in dialogue.
No directly connected 4×4 input mechanism has been identified. The 2×8 trophy import screen provides 16 selectable cells, but no trigger or positional mapping connects it to the candle grids.
The Boiler panels leave their top-left cell unused, but this is not true across the Tomb grids. Coordinate A4, the top-left position in the documented orientation, contains a candle in two of the three Tomb arrangements.
Most classrooms arrange 16 chairs in a 4×4 grid, and some chairs hold homework while others do not. The arrangement is observable, but no correspondence to a specific candle or Boiler grid has been shown.
The Laboratory's Packet Management screens require selecting at least 8 experimental triggers and at least 8 effects from separate 20-option pools. The Satellite Dish adds 8 new options to each pool, while a Blue Tent memo describes SYNKA Court as 8 floors above ground and 8 below. This repeated 8 + 8 structure may relate to the 16-cell candle grids, but there is no positional mapping or confirmed input mechanism.
Randolph's seventh letter in the Mail Room contains a 4×4 diagram showing security door levels. The diagram is a confirmed in-game use of the format; any connection to the candle states remains unconfirmed.
A 4×4 grid is visible at the treasure-map dig spot in the pool. No mapping to the Tomb or Boiler data has been demonstrated, so it may be meaningful or may be a reused environmental texture.

The Boiler Room has 15 panels with the same 4×4 dimensions, while the Tomb adds a third observable state. A comparison under justified orientations and state mappings may reveal a relationship, but no shared symbol or positional mapping has been demonstrated.
The three states can be assigned values and overlaid, but no evidence identifies which grids to combine, how to orient or weight them, or how the resulting sums should map to letters. The disproved universal top-left constraint also removes one proposed anchor.
Reading each row as four bits would produce values from 0-15, but a binary conversion must collapse either empty and unlit or unlit and lit into the same value. No evidence identifies the intended collapse, reading direction, or output format.
A 4×4 layout can support route ciphers or a modified Polybius square, but no route, alphabet, key, or source text has been tied to these candle positions. Fitting a 16-character phrase to 16 cells is not independent evidence.
Four 4×4 grids can form an 8×8 board, but only three Tomb arrangements are documented here and no fourth grid, quadrant order, or chess-piece mapping has been identified.
The Underpass arches have rivets that can be grouped visually into sets of four or eight, and nearby wall panels use 4×4 filled and empty squares. No bit order, repeated value, or correspondence to the Tomb grids has been demonstrated.
The Freezer server lights form on/off patterns that resemble other estate grids. They do not align cleanly with Braille, and no orientation or mapping connects them to the Tomb candles.
The Blackbridge Grotto trophy import screen exposes 16 selectable positions in a 2×8 layout. No trigger, ordering rule, or evidence connects those selections to the 4×4 candle data.
The candle grids may be intentionally unsolvable in the current version. The Dirigiblocks update could introduce new rooms, mechanics, or input methods that give these patterns meaning. Several cut-content elements may be restored.
The repeated 4×4 format may come from modular environmental design rather than a shared cipher. The distinct Tomb states still make the candle arrangements worth documenting, but repetition alone does not prove encoded content.
