The last we heard of her was a mention by Taimi during the PoF story where she was trying to keep Aurene calm after Vlast's death. But then at the epilogue Taimi shows up without her.
During Season 3, Episode 2 Caithe swore she would lay down her life for Aurene. So where is she? Why didn't she accompany Taimi to the Crystal Desert?
IIRC, she also joined Dragon's Watch but none of the other members have even mentioned her. Shouldn't she at least be involved with Joko's invasion of Tyria?
