Splendid - these will do nicely.  I've been doing quite a bit of thinking on the current malaise Sunstrider Isle suffers under.  One possible course of action I had pondered was to collect these arcane slivers from the beasts on the isle.  In doing so, they could be experimented on; this would provide a potential source of culpability.$B$BAnyway, I will tend to the research.  Allow me to place this incantation on you.  I believe you'll make good use of it!
