I remember reading maybe 2ish years ago a pdf that detailed more information on the Olmans and Thanaclan. It didn't look like an excerpt from Dungeon or Dragon, it included a timeline of Thanaclan, and and mayyyybe it had mention of a red flower harvested from the Isle of Dread that could either be used for something like a sun orchid elixir or to extend the life of perishables on voyages. I remember it said something about the meaning of the name Thanaclan being something like "Place of Pearls". I for the life of me can't find it on my computer or in my computer's history.
Did I dream this up? Am I going mad? If what I'm talking about rings any bells, please, help!

None of what you are describing is familiar to me, and I have all of the Savage Tide AP including the Dragon Magazine articles. If by timeline you mean a series of year notations with major events for Thanaclan, that was never published in Dungeon or Dragon in a table. There was just mention of approximate periods of time and major events in paragraphs of text in the adventures.
So what you are describing sounds like a fan-made page on the Internet somewhere for the Savage Tide AP or the Isle of Dread, but I can't find anything now that contains your other specifics.

It could very well be/have been a fan made document/page, possibly one now defunct.
There was a fan-made word document which expanded Tamoachan which was part of the third adventure of the AP. Is that what you are referring to? I had a copy of that document for quite sometime.
If you still have it, I'd very much be interested. Even if it's not what I remember stumbling across, it may have some stuff I can mine for material.

I don't have it anymore unfortunately, but I did find the ST thread (C1 in Wyvern's Wake) here where it was being distributed. There are some email addresses there and the last poster offered to distribute it to anyone who asks for it.
I would DM message a few of the posters in that thread, starting with the last poster. Email if no one responds Someone should be able to help you eventually.
If you do get a copy, let me know!

Starting with the final poster, I would DM message a couple of the posters in that topic. If no one replies, I would email. Eventually, someone should be able to assist you. If you do receive a copy, please let me know! https://paizo.com/Sprunki Game/threads/rzs2h39v&page=3?C1-in-Wyverns-Wake#118

The Isle of Dread is a famous location in Dungeons & Dragons, an island filled with dangers, monsters, and dangerous secrets. You may recall a story or campaign that mentioned Block Blast the Isle of Dread.
