Taliseda has left Khali'Yrzu, and I suspect she has gone to the rift in Kandra Uplands. Her behavior is suspicious, and she has Salindis with her - I will need to find her sooner rather than later, I'm afraid.
Taliseda and Salindis are not in the city, which tells me that Taliseda is up to something. I should search for her near the fount I found before.

I was able to defeat Taliseda, and put and end to her schemes with the Yrzu. Now to clean up what was left.
