Secret Discoveries

Secret Discoveries are a type of Discovery which describe hidden areas or locations which require some effort and knowledge to reach. These areas may hold lore significance, or merely are interesting in their own right. They give a large amount of XP for discovering them. The experience given is not affected by XP Bonus. You can only find them once per character, and need a level minimum to receive the XP. They can involve multiple riddles, items, and locations.

Wynn Plains
The Wynn Plains was the first major area to be given Secret Discoveries in the 1.17 Dungeons & Discoveries Update. The discoveries mainly document Bak'al and the struggles of living during the war.

Desert
A set of Secret Discoveries were added to the Desert of Almuj and the Mesa in the 1.18 Economy Update. These discoveries primarily concern the ancient empire that's once spanned the desert, and the Creden Tibus and the Emperor's Sceptre, both featured in Kingdom of Sand. Additionally, unlike the Wynn Plains discoveries, most Desert discoveries also involve a Wynnic archaeologist named Junes, who is investigating the ruins of the desert empire.

Nesaak Tundra
Secret Discoveries were added to the Nesaak region alongside the Silent Expanse in the 1.19 Update (with the exception of Lusuco's Library, which was made a Discovery in 1.17). They primarily revolve around the conflicts around the Twain family that once protected Wynn, and in particular Theorick, who would eventually freeze Nesaak himself.

Silent Expanse
Ten secret discoveries in the Silent Expanse were released with the 1.19 Update, alongside the discoveries in the Nesaak Tundra. The Silent Expanse discoveries revolve largely around the ancient civilization of the The Olm, the incursions of Wynnic miners through the Abandoned Mines (and the place they settled, in Lutho), and the warping of the region by the influence of darkness.

Unlocking all the secret discoveries in the region requires completion of the main questline, A Journey Beyond and A Journey Further, as well as at least one successful run of the Eldritch Outlook dungeon.

Gavel
Fifty-four secret discoveries in the Gavel Province were released with the 1.20 Update. The Gavel discoveries revolve largely around the War of the Realms, however many are related to the area which they are located in. The coordinates roughly represent the starting point, for a detailed tutorial whilst the pages are still being written, see this forum post. (A Y of 64 means the Y value is unknown).

Dark Forest
This region of discoveries includes both the Dark Forest and Kander Forest.
