Appendix-
[spoiler]As mentioned above, there’s another entry point instead of follwing Dravis’ flower note. This is also considered to be the real beginning of this secret quest. It’s an out-of-game hint though, and since it requires unpacking the game files and at least a minimum amount of technical knowledge, I consider it a lot harder to find than Dravis’ flower note. That’s why I chose to not put it in the beginning of the guide. It’s also more of an easter egg and nothing you have to do ingame.
Inspecting the dead titan in Devil’s Crossing, you might have noticed a texture saying “tagGDX1w not found”.
Now you have to look for that missing tag. After extracting the game files with the Asset Manager executable in the Grim Dawn game directory, you’ll find an entry for that tag in the file \mods\gdx1\resources ext_en agsgdx1_skills.txt. The respective line is:
tagGDX1w=GrimDawn/images/evil
The second part of that line (behind the equal sign) looks like a path or part of an URL.
There’s another clue hidden in the engraving of Sahdina’s Memento. It reads: “The Web we weave carries with it the portents of Evil imagery. - Jay Peggins”. As cryptic as that sounds, there’s plenty to get from it, especially considering the weird capitalization:
"portents of Evil imagery": This creates a connection to the URL type thingy behind the missing tag ("Evil") and it hints at an image file ("imagery"). "portents" means there's more to it than just a simple image.
"The Web we weave": It's on the Grim Dawn website ("web" -> website, "we" -> the developers).
"Jay Peggins": Seriously, jay peg? .jpg!
Now just piece these things together to get http://www.grimdawn.com/images/evil.jpg.
