afroakuma's Planar And Other Oddities Questions Thread VIII

[Thurbane]

I remember seeing somewhere that there is a floating adamantine tower on the positive energy plane that's a gathering ground of sorts for healers/god of healings followers that study rare and weird conditions or somesuch. Was this a random fever dream or something that actually appeared somewhere, and if it's real what do we know about it?

A quick search of 3.X sources didn't find anything. I checked the usual suspects first: Manual of the Planes, Planar Handbook, Deities and Demigods, Epic Level Handbook, Book of Exalted Deeds, Complete Divine and Complete Champion.

Web search only found mention in a home brew setting, where there are adamantine towers on the positive energy plane where it borders with the elemental plane of earth. No mention of them being bases for healers etc.

If it doesn't exist, it sounds like a pretty awesome concept, and someone should totally head-canon it!
