Captain Lucas:
Excellent! Visit either of the 2 Kamalokas we can enter from Dion, kill the Kaneus there and extract their cellular tissues.
You will face the Crimson Hatu Otis and Seer Flouros Kaneus. The Crimson Hatu Otis is much weaker, so I'd advise that you pursue it first.
When you have extracted all the cellular tissues of the 2 creatures, take them to Magister Mirien at the Temple of Einhasad. I know she and the other Sages will appreciate your efforts.
Good hunting!
