While reading the Forgotten Realms:Adventures in Faerûn, I came across a section describing Maran Saya, the underwater Coral Palace of the marid sultan, Biha Babir, located off the coast of Calimshan.

I was instantly intrigued by this setting, but I can't seem to find any additional information. Not even in the Forgotten Realms wiki.

I know this could be a great opportunity to create my own story, but as a new DM (like REAL new, as in, I'm still getting ready to run my first adventure new) I'm not sure I'm quite ready for that.

I'm curious if anyone has come across any other sources of information about Mahan Saya they might be able to point me towards?

Thanks!
