I was reading through Narriseminek's wiki page when I saw this:
The name of Narriseminek's domain is sung and incomprehensible to non-proteans, but is commonly called the Drifting Mountain of Narriseminek the Crownless. It is located within the Borderlands between the Maelstrom and Nirvana, and contains a great temple to the Speakers of the Depths, and the mysterious artifact known as the Singing-Luminous Eye of the Speakers.
I've checked the wiki, Archives of Nethys, d2opfsrd, but nothing I can find even mentions it.
So is there anything I've missed?
