My group is almost finished with D4 – Hungry are the Dead module.
The players have talked about finding the other seals. Have any of the other seals locations have been published?
I don't think so. The Carrion Crown adventure path concerns an attempt to free Tar Baphon, but I don't think it addresses the lesser seals (I may be wrong, I've not read all of it).
The best information I could find is from the wiki:
The three lesser seals were taken, one each, by the armies of Taldor, the Kingdom of Kraggodan and the Knights of Ozem to be hidden far from Gallowspire. The seal in Hungry are the Dead is the one taken by the dwarves of Kraggodan (now the Five Kings Mountains).
So it's possible that another is in Taldor somewhere, but the Knights of Ozem, who guard Gallowspire, could have hidden theirs anywhere. I guess your party would have to go ask them to find out. ;)
There's a lot more about Gallowspire itself in the Dungeons of Golarion book, so that might be another source to look for information.
