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.

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.

Sub-Area: 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:

Sub-Area: Pale Arena
The Pale Arena is a large, combat based room located to the right of the Royal Party. A large door can be found at the end of the room, leading into the arena. There is also another bench, which requires 450 Geo to open. An infinite Soul Totem is found directly outside of the Arena itself. The Pale Arena features two game modes: The arena itself is empty, with a single lever in the middle, and a statue of the Pale King holding it. Switching the lever will ask “Do you wish to begin the Eternal Trial?” Dreamnailing the statue activates the Pantheon of the Wyrm, which does NOT take place in the Pale Arena.
 * Pantheon of the Wyrm: The sixth and final Pantheon, located outside of Godhome. It features harder versions of all the boss fights, some harder than their Attuned/Randiant variants. The Pale Titan serves as the final boss, but does not appear unless he was defeated before hand.
 * Eternal Trial: A game mode similar to trials in the Colosseum, however, features an endless amount of waves of enemies (hence the name). Enemies will continuously spawn, and is a place to simpy have fun with the various enemies throughout Hallownest. This will also feature bosses.
