Every time Fox collects a Krazoa spirit from partaking in a Krazoa shrine test, he must use the WarpStone to return to an area called Krazoa Palace, where he can deposit the spirits. Krystal also visits this area in Star Fox Adventures' prologue where she partakes in the Test of Observation, the only time she's ever playable in the story (outside of hacking), as she's soon imprisoned within a crystal by an unknown force. Collecting all of the Krazoa spirits at the end frees her, but also inadvertently resurrects Andross, who had been manipulating Fox the entire time.

In Dinosaur Planet, this area was known as Warlock Mountain, and was the only location that both Sabre (or Fox, in the December 2000 build of Dinosaur Planet) and Krystal could visit in their otherwise two completely separate adventures, though it's worth noting that the characters that their own sides of the map that were separated by the main chamber room. Like in SFA, every time they completed a Krazoa trial, they'd have to return to the mountain by using their respective SwapStone to deposit the spirits they've collected. Each trek back to the mountain would result in another encounter with their father and mentor, Randorn, as well as other lore dumps such as the Quan Ata Lachu (the "god" of the Krazoa).

Surprisingly, Krazoa Palace also exists in Dinosaur Planet, but as a completely different location than the one that appears in SFA, in this case being Krystal's final SpellStone dungeon that she could access through the giant Krazoa head structure in Cape Claw, after depositing enough spirits. Unfortunately, just like BlackWater Canyon, there appears to be zero design work done in the leaked December 2000 build.

Going by the unused voice lines and also the Dinosaur Planet condensed story, it is here where Krystal and Kyte, with the help of a Krazoa guard who was awoken by Drakor's activities on Dinosaur Planet, would travel back in time to acquire the area's SpellStone. First, they'd head to the future to see that Drakor had succeeded in his plan in resurrecting the Kamerian Heart and thus has destroyed everything, including Sabre, and the now dying Krazoa would hand them the Mind Read spell page and encourage them to go to the past to prevent this from ever happening. From there, they'd time travel to the past, right when the Krazoa and Kamerians (Drakor's race) were having their universe spanning war, and see the Krazoa for who they really are, an extremely evil warmongering race that started the Great War against the Kamerians. They would retrieve the SpellStone from one of these evil Krazoa (who also seems to be a spy working for the Kamerians) and return to the present with questions for the Krazoa, who claims that they have changed since the Great War and promise to bring peace to the universe with the alignment of the Majestic Eight planets. Of course, the leaked voice clips for the last scenes in Warlock Mountain reveal this to be a lie, as the now revived Krazoa reveal they plan on using the power of Quan Ata Lachu to devastate the universe.

This stage was removed in the final Star Fox Adventures, and its name would be repurposed for the reworked Warlock Mountain. Interestingly, early design documents posted by Kevin Bayliss show that even early on SFA's development on GCN, they had still intended on it's version of Krazoa Palace still being called Warlock Mountain, even after its namesake warlock (Randorn) had been scrapped by this point. An early version of SFA's Dinosaur Planet map would even clearly have what is Warlock Mountain at the south pole, though of course this would be revised in the final map.
