A Small Favor

You've been such a good little druid for me, I wonder if I could ask you to do one more small favor.

With the reagents you collected being so finely attuned to Twilight's Hammer magic, they are perfect for a summoning ritual. However, we'll need to take them to the source of their power.

Should you happen upon a conduit while you're gallivanting about the Twilight's Shroud, see if you can't call upon one of the cult's thralls and capture it with this soulstone for me. For questioning, of course.
