Eternal Palace (location)

The Eternal Palace is an area in the Dream Realm. It is an extension of the White Palace created by the Pale King after Radiance was defeated. It is much larger than the White Palace, and includes a series of platforming, enemies, bosses, and more to conquer, with the final boss, The Pale Titan, located at the end.

Added as apart of the DLC with the same name, to access it, you are required to follow Ogrim (Dung Defender) on a small journey throughout Hallownest, ending at the Palace Grounds once the Radiance has been defeated. If Radiance is defeated, it means that the player has already earned half of the Kingsoul, and therefore renders the original White Palace useless. The Path of Pain can still be accessed in the Eternal Palace.

The journey into the palace will also be aided by Hornet, Ogrim, God Tamer, and the Great Nailsage himself, Sly.

Lore
Following the defeat of the Radiance, the once king of Hallownest senses the Knight’s true power. Jealous of his own child’s leadership, the Pale Titan creates the Eternal Palace as an attempt to trap and kill the Knight to prevent them from both the Shade Lord and the Infection, which had died down following the destruction of the Radiance.

How To Access
The Eternal Palace can be accessed by finishing the Ogrim side-quest and Dreamnailing the Kingsmould corpse in the Ancient Basin.

Royal Party
The Royal Party is a large gathering of the bugs throughout the Kingdom summoned to the Palace by the Pale Titan. The event was organized by the Pale Titan to celebrate his re-coronation. He had used his method of calling out towards bugs by invading their Dreams, similar to how he had lured in Dung Defender and the Pale Hunter. The Royal Party is found by entering the first door when entering the main hallway of the Palace. It holds dozens of friends and foes the Knight has met along his journey. The layout consists of eight tables evenly spread out throughout the room. A bench is in between the fourth and fifth tables. A Hot Springs is found next to the bench, and a bar is opened at the end of the room.

To enter the Royal Party, the Pantheon of the Master needs to be beaten. Otherwise, the door will not open and a Seal of Binding appears. The list of NPCs that can be found there include:

Map
The Eternal Palace is a long, deadly gauntlet of challenges. There is no map for the area, as it is located in the Dream Realm. Filled with Kingsmoulds, Wingmoulds, and the new Shade Knights, the Eternal Palace is heavily guarded. After making it past the Palace Gates, you are met with a large, open-space obstacle course similar to large areas such as the lobby room for the Forgotten Crossroads, Kingdom's Edge, etc.

Wingmoulds are set throughout, and there are various Battle Obbles from the Colosseum that roam about. At the top is a spike tunnel that leads into the next room on the right. Using Crystal Dash will bring you into the a flat room. Moving half way through the room will cause the floor to collapse, revealing a bottom ful of acidic water. Stalactites fall from the ceiling of the cave, and and a King's Idol can be found behind a broken wall on the left side of the room.

The next room features a spike pit, with three Wingmoulds set over it. A large upside down hill of throrns raise down from the ceiling, preventing you from being able to Crystal Dash. Moving back to the top reveals a long hallway, with floors breaking to reveal traps of spikes, similar to Deepnest. A saw moves back and forth through the hallway, with a small open gap in the floor in the middle with no spikes. Making it to the end will reveal the next room.

Sub-Area: Palace Gates
The front end of the Palace contains a large gate guarded by two Palace Guards. Defeating the guards will allow access to the rest of the Palace. Beyond the gates is a large front garden, home to several Booflies who provide shade for growing plants on the top layer, and Fungoons whose acidic gases are used to help protect the flowers. Maskflies also live within the area.

The front door is locked by a “White Key,” which is hidden in the garden. You can either break a nearby hidden breakable wall to enter the Palace, or use Descending Dark on a spot in the garden which will bring you underneath the Garden. A single Boofly acts a barrier to an underground layer of the Garden, which holds the White Key.
