With the number of crown crate seasons increasing every 3 months, the wait for the return of a particular one can be pretty long! Here I have compiled (to the best of my knowledge) the dates of initial availability for all crates as well when they were offered on return. I pulled these dates from combing through past crown store showcases and posts on the official TESO Twitter.
