Head to a telegraph pole along the railway track between Citadel Rock and Heartland Oil Fields between 3am and 4am in Red Dead Redemption 2, and you'll find a spider and its web. Place the spider on your map, and you'll find one such location for each of its legs. Right at the centre of the arachnid outline's body, a larger web sits nestled in a tree. It directs you north.
Following that direction will lead to more clues. Guitars and bird carvings, question marks left in an unclimbable mountain near the Calume Ravine. The trail continues from there, continuously pulling you onward in the most indirect fashion. It's compelling and maddening, in equal measure. None of us treasure hunters are even sure we're going in the right direction. We somehow skipped over a glowing pentagram, and a heart left on some scaffolding seems to be part of the pattern? It's all in the air, still.. Sounds remarkably Twin Peaks, doesn't it?
