The Priory tries to find out what the rest of the Scroll of the Five True Gods can reveal, but maybe Taimi also does, most likely... no - certainly wants to find out as well.
Taimi: Nothing on Kralkatorrik, and ditto for... Oh, what's its name? Brain malfunction. Starts with an s...?
I feel like she confirmed that she wants to know this Dragon's full name with this ^
And she still isn't sure what're other letters in DSD's name. Either Aurene will put an end to this mystery, or we will get to see the undamaged Scroll by ourselves in some sort of time anomaly. Alas we got a poem that Trahearne liked, instead of the Scroll in one of Jahai's anomaly. But I guess it wasn't the time to reveal that just yet.
My greatest hope for Season 5 is to finally get in touch with the Water Dragon. That would be awesome.
