The Strange Sigil

In May 2015, a strange image was found in the SteamApp root directory of the game "Crypt of the Necrodancer". Its purpose remained unknown until another glyph was obtained, by snooping through the original image using a hex editor. No clear answers about the images would emerge...

Independantly players of another game, "The Magic Circle" have found a similar image with circles and arcs behind an airlock with a similar image shortly after the game's release in June 2015. It was deemed pointless.

A Shared Mystery

Then, on 23 Jan 2016, a person who knew about the Crypt of the Necrodancer image discovered the same marking in "Mini Metro". Suddenly, people started writing in about seeing it in even more games. "The Magic Circle". "Legends of Dungeon". "Kingdom of Loathing". By a combination of astute observation and dumb luck, the image, coined "the sigil" (from the resource names in some of the games) was now tying half a dozen games together.

In each game where it is present, the sigil is accompanied by a second, hidden circular glyph with little circles, squares and triangles on concentric arcs. While the sigil itself was visible (even though been in vague places or displayed after very specific actions), seeing the second image required completing some challenge, figuring out some devious puzzle planted in the game. In certain cases, the glyph was first recovered using data-mining strategies (i.e. digging through the files and assets of the game), before solving the mystery in intended way.

The Big Picture

After several glyphs had been discovered, it became clear that each of them was a fragment, intended to be joined together to form a larger puzzle, which would become a next clue of the overall ARG. While at first it was not certain how these pieces ought to be assembled, various guesses have been made as to their configuration.

Sigil Pieces Puzzle Tool

You can now give it the puzzle a try yourself with a tool made by DukeBG, making it easy to place an rotate the puzzle pieces yourself. Give it a go!

Clean result:

History of possible solutions to the puzzle (i.e. configuring the pieces into one uniform image) included:

Attempt One	Attempt Two	Attempt Three	Attempt Four	Attempt Five Option 1	Attempt Five Option 2	Current state

Please note that some older versions of the assembled puzzle no longer include all current pieces, as they were created prior to those pieces' discoveries.

Commonality Between the Games

The question of whether or not the games involved with this ARG are linked in some way has proven very difficult to answer. It was first postulated that each game's developers had attended Indiecade, however later discovery of additional games sunk this theory. For now, a consistent, viable theory of connection is lacking. For all we know, the games (and one book) are created by a comparatively small teams or indie developers (with a broad definition of this word). Many of them follow each other on Twitter or know each other in one form or another.

Who Holds The Knowledge

As the ARG developed, some of the developers have disclosed personally and in interviews that... a large number of them don't know where all of this is going. They were presented with two images — the sigil and a map piece — and asked to hide the map piece behind the sigil (we can assume they were not told any particular instructions about hiding since all the developers did it in any way they liked). Moreover, they received subtle assurances that the ARG was nothing they’d be upset about supporting. Some developers seem to hold more knowledge, however.
