Description
I have just the right serum in mind. It will deal with the truth in precisely the way the truth should be dealt with.
For this concoction I will need several Shadow Panther hearts from the Swamp. I also require the enchanted fungus off of the Mire Lord who resides there. I am sure one as able as you, adventurer, can persuade him to part with some.
Now the hard part will be locating a 
Deepstrider tumor from far-off Desolace. Very rarely the giants there become ill and a tumor forms.
Now, off you go!

That Infiltrator in Stonard will surely.... open up... after he drinks my special serum. Haha! The ingredients required are by no means easy to procure. Shadow Panthers are common in the Swamp but collecting enough hearts for our purpose can be daunting. And the Mire Lord can be such a fussy beast. As for the Deepstrider tumor, they are terribly difficult to find. But the chemical reaction I can draw from it is second to none.

Splendid, adventurer! And just in time too. From what Zraedus tells me, the Infiltrator has recovered from his wounds and is ready to be questioned by the orcs. Give me but a moment to prepare the pois - I mean prepare the truth serum.
