Azelf, Mesprit, and Uxie, the Lake Guardian Trio, are back in Hisui to protect their respective landmarks and for you to catch them!
The land of Hisui is a distant past of what would become Sinnoh. This world, even though old, still has a ton of references players will remember if they played Diamond or Pearl.
Game Freak made sure to expand the Pokemon formula while retaining many emblematic elements that made Sinnoh so memorable.
There are many new additions, like the possibility of evolving certain Pokemon without the need of trading them. But, ultimately, Husui is still very much the origin echo of Sinnoh.
Part of this Sinnoh symbolic element is the Lake Guardians. Azelf, Mesprit, and Uxie show up once again, and all three of them are available to catch in Pokemon Legends Arceus.

Where to Find Azelf, Mesprit & Uxie in Pokemon Legends Arceus
You can find Azelf, Mesprit, and Uxie at LVL 70 in their respective lakes after receiving the mission “The Plate of the Lakes” from Cogita.
To get the “Plate of the Lakes” mission, you should complete the main story of Legends Arceus and then follow Volo to get to Cogita. Once you are there, select “The three Lake Pokemon” from her stories.
You can find all of these mythical Pokemon inside the caves in the middle of each respective lake:
- Azelf is located in Lake Valor
- Mesprit is located in Lake Verity
- Uxie is located in Lake Acuity
All these three mythical Pokemon are Psychic types. These battles can be challenging, so take as many Pokeballs and healing items as needed!
