The Ruins of Azlant gazeteer in “Into The Shattered Continent” mentions a sagging sentinel guarded by mongrelfolk on Zanahz-Tahn, but it makes no appearance in The Flooded Cathedral.
Was this not brought up at all because of space constraints? I would think the wyrwoods would mention it, The island is only so big. My issue is that I can’t find any mention of mongrelfolk in pathfinder. Is there a reference somewhere I missed?
