I saw on [GoHub’s photo in their article](https://pokemongohub.net/post/guide/biomes-in-pokemon-go-complete-guide/), there was an encounter with Azelf. I’m assuming people are just thinking Zorua. I tried to find info about them spawning, and nothing. I just encountered Mesprit, and can confirm. They are spawning.
