Well, I wouldn't discount Drowned Sahagin, though I mostly recall the term "Drowned" for the Sastasha HM mobs which are so beyond tempered they've been warped by aether. For the Ixal we have two areas, the Ixali Logging Grounds and Natalan and, while it would not be surprising if Garuda tempered Ixals, I'd have to check in-game if they have any prefix like the Tempered or Drowned (granted, the tempered sylphs go by Sylvan or Sylpheed, so that naming convention may not even mean anything or only apply to the spoken races).

We are getting waaay off-topic, though lol
