We don't really know much else from Gelmorra past that. It required Edda and Nybeth to give it some further plot.
Whatever "further plot" Edda and Nybeth added to PotD, it had literally nothing to do with the Gelmorrans or their culture. Making it useless as a showcase for Gelmorra.

I don't even know if the majority of the dungeon is meant to be Gelmorra at all. We found the portal into it in the Gelmorran ruins, but it seems to be an alternate dimension either disconnected from the true Gelmorra or so warped it doesn't count as history.

We learn nothing of Gelmorra at all, and the archaeologists who were previous working there have been driven out by the Wood Wailers and/or the danger of the portal.
