The Alik'r Desert belongs to the Redguards of Hammerfell, part of the Daggerfall Covenant. Zenimax has stated in a Q&A "The Alik’r Desert has a vibrant ecology, from small critters like lizards up to apex predators such as dunerippers and giant scorpions. And nearly everything in it is either venomous or carnivorous. You won’t be bored – because if you let your guard down, you’ll be dead."
There are 16 skyshards scattered around the Alik'r Desert.
