Talk:Vol.2 Ch.239: 43F - Hell Train: The Floor of Death (8)/@comment-1750668-20170227224143/@comment-26484417-20170301001341

If I had to guess, I'd say that the symbology means "4 fragments of / become 1 Thorn", and--looking at the FoD lore from the perspective of FoD inhabitants--it could be post-Enryu and pre-Hell Joe symbol of their culture / "religion".

And taking Hell Joe's rise to power in the South City, it's possible that it became uniquely associated with the North City faction nowadays.

Or maybe I'm just overthinking it, and it's just something Garam made for herself. After all, she decided to be the one to. Which would make it a unique "quest identifier" that points interested people in her direction.
