Years ago there was another bug report about Ebon Mask when npcs and scripts were changed from EbonMask -> HalloftheEbonMask, because the majority of npcs were on HalloftheEbonMask.

Based on your bug report, I did some more queries and found 2 npcs which still gave faction adjustments towards EbonMask, despite there being no npcs actually having the primary faction of EbonMask. I have changed these to HalloftheEbonMask. I also looked into any quests which might adjust EbonMask.
There is confusion on the allakhazam page about whether or not both factions did exist.

That being said, I don't think HalloftheEbonMask was ever actually real. I can't find any research pointing to an actual source.
However, I do see in-era research for EbonMask:

What I think should probably happen is to rename HalloftheEbonMask to Ebon Mask and EbonMask to HalloftheEbonMask. All the npc factions and quest factions will be aligned to EbonMask with little effort.
If anyone has an in era screenshot or log mentioning 'HalloftheEbonMask', post it up.
