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, <name>, 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!
Splendid, <name>! 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.
